I mean, you’re always allowed to join any meme stream you want, and i don’t think we have the ability to prohibit certain people from joining. Idk, maybe I’m wrong here.
But reformed christians believe that scripture is the word of God, so it has ultimate authority, and reformed folk believe it’s understandable. And with that said, scripture shows that God created humans male and female, and God created marriage to be between one woman and one man. Scripture also says that homosexuality, along with all other sins, results in separation from God, and judgement.
So no, reformed believers cannot support LGBTQ+ in any way, but we’re supposed to love our neighbors, even those who hate us.
