Genuinely interested - "I do believe people find the concept of gender identity helpful,"
As someone who doesn't have this feeling I find it hard to understand - obviously really! I can believe that others have it - I'm an atheist but understand and accept that others have spiritual feelings, ditto for having a "minds eye" that I recently found out was actually seeing stuff as I can't do that either.
How and why is the concept of gender ID useful? Sex dysphoria is different, again, I get that. So not about sex but gender, gender ID, I genuinely can't see the concept as anything other than regressive - "ladybrain"- and vast amounts of output from trans orgs and trans people say this is what it is to.
No one has ever asked the general public if they have this feeling. Trans people do, by definition, but this has been extrapolated to everyone. I don't think it's correct.
Also for women who are feminist, many of us became feminists because when we were young we noticed we were treated "like women" or " like girls" and we didn't like it, we wanted to be treated like people. Trans ideology says that "cis" women and girls like to be treated that way, and to treat anyone who indicates that they want to be seen as female another way is an insult. Many women are it all as extraordinarily regressive.
I am really interested to know how it's helpful. And how helpful is it if in fact most people are "agender" "non binary " etc
