Nah, it's a comparison.
The reason being GC is compared to a cult is that it's taken over lives. There is study (of each other's ridiculous origin myths for trans people), a significant loss of friends who don't share your beliefs, ignoring of the very significant character flaws in leading figures, and - most of all - loss of outside interests.
The attempts to forcibly detrans trans people via denial of care, and to place them in grave danger of violence by relentlessly vilifying them, are the reasons for the phrase trans genocide.
Minorities get to describe their persecution and those who persecute them, as they see fit.
Look at this forum. Someone is currently proposing boycotting a company because they are considerate towards trans/nb people's needs.
That's it. Not because the company's harming women (take a look at the very decent provisions for female workers). Just because they don't hate trans people and recognise they may have extra needs.
That is cultish behaviour.
It's also the behaviour of people who want trans people not to exist anymore. Though quite what you'd do with your life if they didn't - what would you do with all that extra time?
Perhaps comparison to QAnon would be more appropriate. Reading the Queer Milk panic reminded me of Pizzagate, and of studying The Crucible.
I'm sorry you have experienced a cultish church, that's awful. But don't you recognise some of the hallmarks?
The keeping people in a state of terror and paranoia as means of control?
The othering of anyone who speaks against the group's beliefs?
The repetition?
The removal of friends who might extract you?
The single subject of study?
The consultation of sacred texts?
The exhortation to pay into crowdfunders and buy merch to keep cult leaders going?
The way some people appear to have got very rich by telling their followers to give them money?
It's exactly the same mechanism as something very familiar to me: domestic abuse.
I'm an abuse survivor who's helped others leave their abusers. I know what I'm talking about. I usuall.do it by comparing leaving DV to leaving a cult.
I know this forum gives me PTSD flashbacks, and why: it's packed with people who are so angry at their targets, they'll attack anything they do.
You know how you try to placate an abuser? They don't like the way you dress. Or talk. Or have friends. So you try to change. But eventually, they are so desperate to get to the high of telling you you're evil that they punch you for opening a door too loudly. Putting a plate down at the wrong angle. Even, appearing in a room.
That's where a lot of posters are at on this forum now. Definitely not all, but a hardcore of abusive people who have radicalised themselves and now hunger for news of What The Trans Have Done Now.
They're being treated decently by a nut company! One's appeared on TV! One fell in love with a cis guy on I Kissed A Boy! There's a Pride Progress flag in Morrisons! Someone famous has says they love their nb child! Feeding time!! Come and hurt them!
Every abuser hates their target, and feels utterly justified in 'punishing' them. They demand conformity and say they've been really tolerant up til now but their target's gone too far. The hate gives them validation and peace.
Seriously, what would you do with those extra hours?
Or is the pull of hate too addictive? Because look what they made you do.
Look what they made you do.
