They already conceded that hetero anal sex must also be considered immoral to maintain the view. Here’s what I’ve got; Anal isn’t a necessity. Homosexual people shouldn’t be framed as immoral simply for engaging in basic parts of life based on their sexual nature. Homosexuality isn’t inherently harmful and certainly not immoral. It’s not their fault for being the way they are, which isn’t wrong in any way, and it’s also possible to use protection to prevent STDs.
