Because if you did, you'd learn that Muslims are normal people. Some are assholes, some are not. Some are straight and homophobic, others are proudly queer. You could argue that Islam is bad because it encourages homophobia, that's an acceptable opinion. But saying that all Muslims are homophobic is bigoted and just plain wrong. The difference between legitimate criticism and hate is not hard to understand… unless one wants to blur the line, probably to hide one's hatred.
