That's like asking if there are good gamblers, or good porn-watchers, or good...
There's plenty of people, some of whom I know, who are good people despite their flaws, because even if they haven't been capable of rooting those flaws out they at least don't allow themselves to become consumed by them, and have other redeeming qualities to boot.
I know one gay dude who has avoided the siren call of easy lays and absolute promiscuity who seems like an alright fellow, and so regardless of how personally disgusted I am at the idea of fucking another man, this one guy at least seems to comport himself in a prosocial, restrained way.
