There are, unfortunately, certain fundies who do, indeed, believe that being forbidden to hate, or preach hatred towards, homosexuals amounts to an infringement on their freedom of religion. It is a sickening attitude. Why weren't these people taught "live and let live" when they were kids? Why on earth do they think it is their business who other people marry, or sleep with? And how on earth do they reconcile bullying or outright violence towards gays with their God's commandment "love thy neighbour?"
Go read your precious Book again, guys! It doesn't say "Love thy neighbour unless he's a fag; if he's a fag you can kick his ass!"
Anyway, get over yourselves. It's not persecution just because you're not allowed to persecute someone else. And you can still hate them all you want, no matter what your God said about that. You just can't commit crimes against them just because they're gay.
