The Sydney Sweeney meme was pretty sexist. There are semi frequently memes where the centre of the joke is a woman’s body, where I will find gross comments as well.
Most of the memes are fun and trans positive, but there is definitely a pattern of objectifying and sexist jokes that are not being moderated (as I said, I do report but no action is being taken). I have also found the community very hostile against observations of sexism, which absolutely does not help. Personally, as a trans masc person who has experienced a lot of sexism on the internet when I still presented as femme, I do not feel welcome there.
