Yes there's a phrase that comes up "Love the sinner,but hate the sin"
Very familiar with it.
Unfortunately, IME, many who say it don't really live it. They seem to conflate the sin with the sinner, and go right ahead being unkind to the sinners in question.
I have noticed a few clergymen who have also recognized this, and have started to address the issue from the pulpit/altar, in an effort to change the behavior. Slooooow going, that.
When I get into a discussion of homosexuality on those grounds, I try to remind all participants that, according to our shared faith traditions, we're ALL sinners in some way. Then I point out that we don't generally act like asses to sinners of OTHER kinds, and ask what sets homosexuality apart from this other sins so that they get beaten, insulted, fired, refused service, evicted, etc.
There was a VERY thoroughly out gay guy- who was also a Wiccan- in one of my gaming groups. He had the misfortune of working alongside a staunch evangelical. He used to talk to us about her latest attempts at conversion, etc.
I told him he needed to make a hostile workplace complaint.
I realize that evangelicals take evangelization seriously, but it doesn't belong in the workplace. AND, since she seemed to be singling him out as the sole target of conversion, it really was inappropriate.
