Yes, It's (At Least Partially) About Repressive Sexual Mores

I'm reading a book about Justice Brennan, and a chapter I read last night discussed the very important case Griswold v. Connecticut. It mentions how, around the time of Griswold, the Catholic Church was beginning to debate itself about whether or not it ought to think birth control was unacceptable. And it quotes some Pope from shortly before that era, probably Pius XII, saying that birth control was not okay because it was "mutual masturbation...gaining pleasure by an unnatural act." Which brings me to my point: yes, this is about an anti-fun ideology. By "this" I mean, very broadly speaking, every aspect of the modern Christian conservative political movement's desire to regulate all and sundry forms of sexual behavior. Birth control, gayness, abortion, premarital sex, all of it. It's about being anti-pleasure. Having too much fun in the wrong ways is considered a Sin. Why? Unclear. Who does it hurt? Why does god mind, if he does? Is it that, if we like this life too much and have too much fun here, we won't be sufficiently attendant to some sort of supposed future life? Or is it just that a bunch of old men think that young people having fun is disturbing to them, personally? Probably a heavy component of this last one. But in any event, we do know that the old line about how Puritanism is the haunting fear that someone, somewhere is having fun applies more broadly than Puritans per se.

Side note: I do admit that there are legitimate reasons to be opposed to abortion that do not involve being anti-fun. I myself don't think that a pro-fun position is sufficient to make abortion good (in fact, I don't think anything makes abortion good, I think certain circumstances make abortion least-bad and that the government shouldn't criminalize it), just as I don't think a pro-sexual privacy position is sufficient to make it constitutionally protected (though I do think it is constitutionally protected). But I think as an empirical fact the anti-fun movement is a considerable part of the anti-abortion movement.
