We are going through some crap lately and I used reddit for therapy and general bitching at strangers for being stupid.

This will sound random but have you thought about joining mumsnet? It's probably the 'terfiest' place on the internet, especially the Sex and Gender forum. It turns out that when thousands of women come together to talk, with an initial interest in motherhood, pregnancy, miscarriage, trying to conceive, etc, they tend to understand biology. And after a while 'be kind' turns into 'what the fuck?' It has a pretty unique tone but once you get used to that it will fulfil your reddit needs while also being someplace that you can talk relatively freely about how some people's gender identity is affecting everyone else and what we can do to protect our children. (And the Am I Being Unreasonable forum is great for bitching at strangers for being stupid. Also entertaining car parking threads.)

Aaannnddd think about what a massive 'fuck you' it will be to your husband when you tell him that you have joined one of the biggest parenting forums on the internet and all the mothers there share your concerns. (Or if you want to be more grown up, plenty of women talk about how to find a way to discuss this with their husbands so they can understand why they are so concerned and find a way to improve your relationship, at least as far as this topic is concerned.)

The main forum re-gender issues is here, just be careful about using the term autogynephilia as that can get your post deleted but you won't get banned for it. https://www.mumsnet.com/talk/womens_rights
