I've seen many "christians" (really just right winged pharisees) say that being gay is a sin, which it is not. I will show you why.
Many Christians quote Leviticus 18:22, which doesn't really work. Here's the verse for clarity: Leviticus 18:22 (ESV): 22 You shall not lie with a male as with a woman; it is an abomination.
This doesn't really work for one reason: it only talks about sex. The only thing said here is gay sex is a sin (which isn't due to lust, but instead due to God intending man and woman to marry, so it fits under fornication fyi), nothing about gay relationships like dating, crushes, or earthly marriage without sex. Being gay is not a sin. Say it with me here: BEING GAY IS NOT A SIN!
