Fuck the people disparaging the religious, but it should be noted that atheism IS an extreme religious minority and a large percent of western socialists are LGBT+ people that have been abused by organized religion. So a little respect from both sides should be given, and maybe don't say lol fairy tales or lol fedora (cus again atheism is a minority everywhere, you probably wouldn't speak about any other religious minority that way).
And no Islam isn't inherently more sexist than any other abrahamic religion, afaik it's actually better (but this varies wildly like any religion)
