We are so fortunate that this discussion is allowed on this site. Reddit has removed every single gender critical subreddit from it's pages.
I was on the Buffy subreddit discussing the Joss Whedon allegations and it's full of comparisons to JKR. How people can still love a franchise despite its creators etc. The irony is that JKR receives more abuse from people who are cancelling someone else for abuse!
I was banned from that subreddit because I corrected someone and said that giving birth is synonymous with being a woman. I received a temporary and was told that if it happened again the ban would be permanent. So I pointed out that in the UK, only two trans men have ever given birth vs millions of women, and so my comment was factually correct. So they made it permanent.
Can't say I'm a fan of the Harry Potter shite being everywhere but I fully support JKR and always hope she's coping well. The level of hate is unlike anything I've seen and all of it is completely undeserved.
