Most Christians world over still believe unrepentant LGBT, people of different religious beliefs, who have no marital sex etc will die in whatever flavor of Revelation apocalypse they have.
Believing that their execution is imminent for such things is hateful. Believing that it was justified before Jesus is also hateful.
The numerous biblical genocides would still be the work of a monster.
Tl;dr: if you believe executing people for being gay was, at any time, for any reason justifiable, you're hateful.
Yes... there are all types of Christians beliefs that run the gamete - just as there are LGBT churches too.
But it doesn't change that the message of Jesus was love and not hate.
