I have to admit I can, very easily. I'm not defending the church's record on homophobia, which is largely (though not exclusively) abysmal, and I really do wish the church would rethink things, but it's not a uniquely faith-related issue.

You can have a totally toxic conception of 'manliness' and 'womanliness' which leads to homophobia without being Christian; or it needn't sit easily with your Christianity (see also: the type of fundamentalist who's uneasy with the 'girly' Jesus they see the church as promoting, where 'girly' means 'not macho'). And the homophobia of the Nazis wasn't justified in religious terms, but in terms of what was "natural" and what would promote lots of Aryan babies.
