When evil is folded in (and it does not take rocket scientists to tell you buggery is mean — why would it be so commonly used to humiliate enemies in pagan culture?) it stops being love. It isn’t a matter even of elastic limit, it is a matter of something WRONG being incorporated.
I’ve noticed that the leftists take a term then expand that term beyond its accepted meaning. Your interpretation is interesting “incorporation theory” I’ll call it.
