The Bible encourages to commit crimes against people that do not obey their obligations. Fortunately, an overwhelming majority of catholics reject the use of violence. About sexual orientation it is very specific:

Leviticus 20:13
"If a man practices homosexuality, having sex with another man as with a woman, both men have committed a detestable act. They must both be put to death, for they are guilty of a capital offense." (NLT)

I meant the earthly court, and before God everyone will answer for their sins.

Loving people isnt a sin, not that sin exists anyway, but you get the point.
