I don’t think the Muslim community as a whole is an ally to the LGBTQ community, but to believe that this is an isolated problem that can be attributed to one single community is dishonest. By thinking that homophobia is isolated to specific communities along ethnic or religious lines and not economic or educational ones, you’re replicating homonationalism.
You can and will have the same experience as an LBGTQ couple in a poor neighborhood inhabited by Muslim immigrants and a poor, conservative neighborhood inhabited by predominately white people. I would not want to hold hands with someone of the same gender in a rural Polish/Hungarian/East German/etc village.
You know, you can find the unjust bombardment of the Gaza Strip (and now also the West Bank unfortunately) wrong, and not compare it to the Holocaust at the same time?
