On the other hand you also don't change ideas by mocking others and denigrating them.
I agree that religious communities that vilify LGBT+ or any other group are toxic and shouldn't be tolerated... but groups that vilify all religion as toxic, whether religious people hold those beliefs or not, are often toxic as well.
You obviously don't (often) have atheist communities calling for death threats and concentration camps... but they do often tend to end up being echo chambers for hate and anger. That's not the kind of positive community I would want to be a part of, and I'm not religious at all.
