Traditional Christianity does, and always has (iow it's not extremist or extremism, although if one were to accuse traditional Christian ethics of being extreme or extremist I would suspect the accuser is confessing through projecting). It's not just the Muslims and the Catholics who think this way though, Buddhists too. The Dali Lama himself said it's misconduct.
Depends what you mean by blaming. Are they accountable, responsible, for their view? I say yes they are, which is just like all the rest of us. I'm responsible for my views. But have I been deceived and tricked, at times, in my life? Yeah. So am I fully responsible, if I've been lied to by someone I might have trusted? I can't really give you a yes or no, it depends. In a sense being hoodwinked isn't my fault, but on the other hand, "Fool me once, shame on you; fool me twice, shame on me."
So idk. I guess a part of me could say I can blame them. But really I'm not interested in blame here, I'm interested in protecting kids from getting into bad habits as children, tantamount to falling into a deep pit, because they were tricked while young and defenseless, into making an almost irrevocable life choice, which leads them down a gloomy path.
I posted the tweet with the meme because it's not said enough, that the traditional Christian view of the matter, for those with this ideation, is celibacy. It's not any sort of condemnation to not be called to the vocation of marriage. Those with these desires are clearly not called to marriage. Perhaps the psychological cause will be isolated one day so that it can be healed, but rn we all know it would take a miraculous cure for a Pride person to see things a different way. We just have to accept them for who they are, and not try to make them something they're not.
