Muslim is a religious designation. People who don't believe in any gods and think religions inevitably become corrupt are not going to care all that much.

Your identity as Muslim does not affect whether I give a fuck about you. I want everyone to have life, health, dignity, and personhood. I don't care what their religion is.

And sure, I disagree with some Muslims who are authoritarian, or violent, or misogynistic. I also disagree with Christians who are authoritarian, or violent, or misogynistic. It's the authoritarianism, the violence, and the misogyny that I take issue with.
