The above (from CoffeeTeaChocolate) sums up my feelings about this issue perfectly (thank you CTC).
I wouldn't describe myself as a GC feminist - I'm just a middle-aged SAHM who wandered in here a year or so ago and became increasingly horrified and angered by the current trans idealogy.
My female socialization (if that's what it is) is very strong. I was raised to believe I should be kind and considerate and put others needs ahead of my own, and have often compromised my own feelings and safety because of this. I was sexually abused as a child because I had to 'be kind' to my neighbour's teenage son, who had a learning disability, and as a young women, I fell for many a 'sob story' from men who were trying to get into my knickers (and I don't mean wanting to wear them). So I know, first hand, how manipulative men can be and I've no doubt that some will take advantage of self-ID to abuse women and girls.
On the other hand, my natural instinct is to be sympathetic to people who have gender dysphoria, and to anyone who is abused or shamed because they don't fit into the usual gender stereotypes. So I often find myself wondering (as in that David Mitchell meme) if I'm the bad guy.
But, in the end, as CTC says (much more eloquently than I'm managing to) the safety of women and girls is more important than the validation of transwomen's feelings - and if transwomen really do consider themselves women they should understand that. Some do of course. I've watched some of the Blair White and Rose of Dawn videos - and they clearly get it; but many others are just 'me, me, me' and couldn't seem to give a toss about the genuine and reasonable concerns of natal women - while expecting us to fall over backwards to accommodate them. Seems like fairly typical male behaviour to me.
As for the cancelling of the Reddit site - I never really looked at it, as any time I've accidentally wandered into Reddit I've got the impression it's Incel HQ - and quickly wandered out again. Given how nasty it seems to be in there generally, it seems unlikely the GC bit was cancelled for nastiness per se - though I don't think it was misogyny either. Rather, it seems that trans people have some special status, which means they must be protected from all offence, but are allowed to insult, harass and even threaten 'cis' people, especially women, with impunity. So much for 'cis' privilege, hey!
