If Muslims want to support LGBT that's good. I don't oppose a Muslim group that advocates marriage equality and gender inclusiveness. I do think that other Muslim groups will see this negatively. Still true Muslims. I sometimes feel a deep hatred towards Islam and I like to focus on good things about Muslims because I know I should not generalize.
