I'm sorry, but No Shit Sherlock.
The reaction you are getting is not because no one wants to listen, it is because we know this. It's bloody obvious. One of the eye opening things about finding one of your core values no longer aligns with your "tribe" is reading across the divide and seeing what bias is in the messages they are getting, and how that also illuminates the bias what your side is getting.
I have to admit I was a little disappointed by your suggestions of practical steps because honestly, it's what smart people do anyway, and did even before social media and manipulation ramped up the stakes. Trace stories back to sources you trust, to named people if you can. Constantly cross check taking different points of view, and with what you already know - do things still stack up? Argue with yourself constantly. Assume the people who disagree with you, while maybe wrong, are acting in good faith, and be aware the ones who align with you may not be who they seem, may have have an agenda.
Trust long, well argued posts over short ones. Play the argument not the person. Avoid thought terminating characterisations like "Facist" or "Woke" to make an argument and go back as often as you can to the first principles/values that you base your position on (hence the long posts).
A handy rubric for me is when you come accross a story that makes you go "Yes!", that seems to align to exactly what your own perspective is, either agreeing with you or gosh-darn just a great example of exactly what the other side get so wrong, be wary. The world is complex and there's always nuances, compromises and less-than-we-might-like.
It's a few years ago now I think, but FWR had a great accidental education session from a group of TRAs (there is statistically significant over-representation of trans identifying men in technology - did you know that? How do you think that has distorted the neutrality of tech platforms on this social phenomenon?) trying to use an early GPT to outsmart us. Spoiler - it didn't work, because GPTs do not form a logically coherent position to argue from so the longer you debate with them, the clearer the gaps in their logic are. It's worth finding that thread if you can - given your background I think you will be interested.
But as several PPs have pointed out, this has gone beyond just "what people are saying on the internet". Laws that undefine womanhood as exclusively female have been enacted. Women have been slandered as Nazis - Nazis - and hounded out of their jobs. Men have been taken part in Women's sports. Male rapists have been considered suitable for inclusion in women's prisons. Young women's understanding of Feminism and of the reasons they never seem to get the same traction that men do has been undermined by the diversion into gender identity politics, persuaded the belief that "a woman is more than her body" means a woman can have any body, as if allowing men to claim to be women will somehow defang the sexist stereotypes and biases women face. The Denton's docuemnt, unbelievable as it seems, was not a hoax, it was available on Denton's website for some time. I downloaded it myself.
No doubt the social pressures that pushed for these changes were inflamed by bad actors, but they did and still are happneing. Doing nothing is not an option.
The Democrats called this one wrong. They do need an honest converstaion on gender identity, one where they ask themselves "Why do we believe this? What does it mean for a person with a male body to be "a woman" and what does that mean for everyone who up to now considered herself a a woman because she is female. What does it mean for the rights and political voice of women and of female people, if womahood is a feature of the mind not the female body? How exactly did this belief that is so clearly full of gaps and contradictions come to be such a defining feature, even a test of loyality, for us and our supporters? Is this really who we are or were we fooled and lead here?"
BTW, I genuinely would like to hear your thoughts/analysis on the un-overseen powers that accrue to people in the tech industry and to mods of popular platforms - people who do not need to say anything or be visible at all to wield significant control over what people are able to view, and in the case of Reddit, TikTok, Facebook etc created the impression that almost no one was questioning the genderist position. Like many others I have seen this happen in real time as one side of a conversation was simply censored away, with anyone not there at the time it happened to see the actual posts that were made being given a completely different description of the event afterwards.
