Jesus is well known for Loving people, but never once did He ever endorse sin.
All Christians know (by His example) that we can and should Love people, without accepting/approving the evil deeds that people are at times inclined to.
Condemning an ACTION is not the same as hating the person engaged in said action. If for example, my son stole a dollar from me, I would still Love him, but I would rightly condemn his thievery.
The idea that rebuking wrongdoing is bigotry toward the person engaged in the wrongdoing is utter nonsense.
