The other thing that might be useful for you @helpamamaout is the bbc programme No More Girls and Boys. Not wacky, as the title might imply. Very sensible programme.
It demonstrates, quite chillingly, how children are programmed from the off into femininity and masculinity.
At the age of seven, the only emotion the boys could adequately express was anger, and, when asked, the girls said the only thing they could do better than the boys was 'look pretty'.
That's gender.
It's damaging and insidious. The trans-ideology will have you assert that it is innate. Not learned.
But gender (masculinity and femininity), change over time and geography. A few hundred years ago the wealthy men in this country wouldn't dream of leaving the house without their wig, make up and in heels. Pink was considered masculine - as a lesser shade of red. In America football is a girls' game, and considered feminine. (Boys play American football).
The trans ideology says that if a man feels feminine, he must be a woman, because only women feel like that. It's regressive, patently not true, and something that many women have railed against since forever. Hence gender critical.
Historically women were considered to be too irresponsible to be financially independent (even in recent history, mortgages had to be countersigned by a man), too dim to be educated at university, not educated enough (ironically), to vote, and men were considered entitled to sex whenever they wanted it, if they married a woman. (Rape within marriage was only made illegal in the 1990s).
Deeming women irresponsible, dim, uninformed, and available for sex 24/7 is gender stereotyping taken to the extreme. And obviously highly sexist. And equally obviously, incredibly common!
Gender stereotyping tends to disadvantage women much more than men. Look how women are deemed emotional (irrational). But look at any man after his team wins, or loses. Or male violence. It doesn't get more emotional than that.
The reason why feminists were the first people to notice the damage the trans-ideology causes is because they are very aware of gender in the first place. And how it is used to keep women down.
