No it's not. That's a ridiculously dumb thing to say. Being gay isn't a religion. Being Muslim is a choice, being gay isn't.
If I don't believe in a magic imaginary sky fairy and find the whole concept of what is necessary to subjugate oneself in worship of said sky fairy to be ludicrous, in what sense would I have any respect for any segment of the religion, especially one that promotes hatred of others in a book that is meant to be regarded as "perfect", "incorruptible" and "the absolute final word of the one true God"?
Hating MUSLIMS is the definition of Islamophobia, just as homophobia is the hatred of homosexuals. Hating the religion is not. The more conservative Muslims are trying to change the definition for it to mean hatred of the religion, but nowhere in the world (except maybe Saudi Arabia) is it considered taboo or immoral to voice opposition to a religion. That;'s why we're allowed to criticise Christianity and not be observed as "Christianophobes".
