Sorry for saying this but in Christianity you can simply look at the "Love Thy Neighbour" tale and ignore the rest of the bad things. This is what my friends do and it's theologically viable if you believe that commandment from Jesus is more important. Leviticus hates gays but Leviticus also supports slavery and atheists seem more concerned about it than Christians .
Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
