The group is focused on a living leader to whom members seem to display excessively zealous, unquestioning commitment.
Closest you've got is Posie Parker, who's racism and constant platforming on white supremacy channels seems to be completely forgotten, though the unquestioning support of Marion Miller (on trial for accusations of amongst others, homophobic remarks towards a police officer, which are never even mentioned, because she also Rallies For Your Cause), late Magdalen Berns (for verbally abusing trans women), Maya Forstater and all the other folks are of note.
The group is preoccupied with bringing in new members.
The very premise of interest in 'peaking' people, or people having 'peaked'.
The group is preoccupied with making money.
Bi-weekly Crowdfunders, latest probably being James Esses, fired from a child helpline for pushing unlicensed therapy on children with the effort to steer them away from being trans (conversion therapy) and being booted from his therapy school for wanting to use the profession for conversion therapy (as well as his severe breach of safeguarding guidelines in his previously mentioned volunteer job), or the Miller crowdfunder that was booted for violating the websites' terms and conditions which resulted in her claiming to want to sell her house, which steers to The group teaches or implies that its supposedly exalted ends justify means that members would have considered unethical before joining the group (for example: collecting money for bogus charities), as her complaint before was that she shouldn't be arrested because being away for a night or two would distress her autistic sons, while permanently selling her house to win a relatively minor case, completely removing them from their normalcy, is fine suddenly.
Questioning, doubt, and dissent are discouraged or even punished.
Cathy Brennan versus WoLF comes to mind - the former being ridiculed and excommunicated because she didn't tolerate WoLF allying with the Heritage Foundation regardless of it's misogynistic and homophobic entire existence.
Mind-numbing techniques (such as meditation, chanting, speaking in tongues, denunciation sessions, debilitating work routines) are used to suppress doubts about the group and its leader(s).
Being so obsessed in "ribboning", because someone in trial for an accusation of homophobic/transphobic hate crimes decided to stalk someone to take pictures in their home environment, that you completely forget that the act is a) illegal and b) reflecting incredibly poorly on any company still willing to advertise here comes to mind.
As does plastering 'woman = adult human female' everywhere, followed by the predictable outcry of 'silencing' when it gets removed, even though you can't fling a rock in a pile of newspapers without it hitting one with an article from some poor unheard silenced deplatformed gender critical voice.
The leadership dictates sometimes in great detail how members should think, act, and feel (for example: members must get permission from leaders to date, change jobs, get married; leaders may prescribe what types of clothes to wear, where to live, how to discipline children, and so forth).
You literally ask each other about things you collectively decided to disagree on without, evidently, any personal thought.
The group is elitist, claiming a special, exalted status for itself, its leader(s), and members (for example: the leader is considered the Messiah or an avatar; the group and/or the leader has a special mission to save humanity).
Any cis woman who isn't "gender critical" gets called a 'handmaid' and everyone else who isn't "gender critical" gets called an MRA, where only "gender critical" people are truly looking out for cis women's rights (don't pay attention to the anti-abortion activists, racists, homophobes, ableists, antisemites and otherwise threat to all or significant groups of women in the back).
The group has a polarized us-versus-them mentality, which causes conflict with the wider society.
Help help my husband thinks I'm transphobic should I get a divorce.
Help help my family and friends have estranged me because I'm obsessed with trans people, this does not reflect on anything I'm doing at all.
My otherwise lefty friends are men's rights activists, how dare they complain about me asking the Helen Staniland question every time trans women get mentioned.
The group’s leader is not accountable to any authorities (as are, for example, military commanders and ministers, priests, monks, and rabbis of mainstream denominations).
Posie Parker, who's free to call for trans men to get sterilized, trans women to die slow painful deaths (though, given I've seen a number on Spinster celebrating trans women being murdered, dying or being abused, that shouldn't be a surprise), make surplus racist comments, invite herself over to white supremacist shows. Bilek's fifteen months of fame taking antisemitical theories from Keith Woods, noted neo-Nazi. Helen Joyce who took those same theories from Bilek, the billboard guy who harassed women on the streets.
No real 'leader' and no military or rabbi's or whatever, but man do the main figures in your shitshow get away with everything as long as it's not targeted at others of your own.
The group teaches or implies that its supposedly exalted ends justify means that members would have considered unethical before joining the group (for example: collecting money for bogus charities).
The ties to the Heritage Foundation.
The lawyers that are anti-abortion activists.
The speakers that are anti-abortion activists.
The movies involving literal practicing, conversion therapy website listed, homophobic conversion therapists.
The constant sexual harassment.
Selling your house for a relatively minor lawsuit because winning it might mean gender critical thinking gets defended by the law.
The leadership induces guilt feelings in members in order to control them.
If you don't participate enough you're literally throwing children into a pit of hormones and surgery and getting every woman raped because that's how society will be if the transes get any semblance of respect.
Members’ subservience to the group causes them to cut ties with family and friends, and to give up personal goals and activities that were of interest before joining the group.
Gender critical people spend more time talking and thinking up make-believe stories about trans people than trans people spend time thinking about trans people.
There's surplus stories on this place alone on people cutting ties or having ties cut with people because you can't stop obsessing over hating us.
Members are encouraged or required to live and/or socialize only with other group members.
A little bit of column 'trying to peak everyone', a little bit of column 'everyone who's too positive towards trans people is a handmaid/MRA and the enemy'.
