I've seen a bit of these types, but usually they wore iron cross rings, or white robes (KKK). Even some of the more extremist Christians I know haven't acted quite like that. Yes their preference is very much against homosexuality and more liberal policies of "Do what you want as long as you don't harm others", but I haven't seem them go out of their way like the extremist liberal ones do.
I've even been screamed at by some extremist liberal woman because I (a male <shudder>) dared to walk through a door and hold the door open for her, err, hir, err, "it". And note, even if you can't see it, am a bisexual male.
