I think if “Love the sinner, but hate the sin” is supposed to be treated with anything other than hilarious contempt, then it stands to reason that the same structure can apply back:
It’s okay to hate the religion, but love the people.
It must be, if it’s okay to “hate the sin but love the sinner.” Just trying to be consistent, here.
So, conversely, I suppose it stands to reason that if “Hate the religion, but love the person” tastes a bit bitter in the mouth, then maybe – just maybe – we can show that “sinner” homily the door.
Myself, I wouldn’t have constructed such a crazy statement in the first place for exactly this reason (seriously — who’s writing these dumb-ass homilies?), but my stance on the matter mostly concerns a worldwide increase in compassion and kindness, which divorces it from most of the major western religions anyway.
