What makes adult content "degeneracy"?
Nobody cares about your opinion of what's "degenerate".
> The developed world has a fertility crisis.
Nobody cares about your opinion of how many people there should be, either.
It's decoupling what shouldn't be decoupled in order to optimize what shouldn't be optimized.
Rather like how your employer's janitors are from a service company, your uber driver is an independent contractor or whatever, your mortgage has probably been resold like five times, etc.
All examples of having more complex interactions stripped out.
People can do stuff for fun, because it feels good, or for whatever reason. Not everything in someone's life has to be done for a direct survival goal. People go for runs because they want to be fit or achieve personal goals, (probably) not because they want to be better at outrunning a boar that they're hunting.
You're mistaking "Fuck off" for an argument.
The person I was responding to expressed the belief that the law should constrain other people's choices, on threat of punishment, in order to (a) reduce "degeneracy" as that person sees it, and (b) "encourage" the other people to act as breeding stock. In other words, to draft everybody else to implement the world that person wants to see, and to hell with their own preferences.
I don't have to argue against self-evidently Nazish bullshit[^1]. There's no factual question anyway[^2]. Either you're willing to use others that way, or you aren't. And if you are, you don't get my charity.
The whole point is to tell them to go away and stop bothering decent people. They are bad, they should feel bad, and, more importantly, anybody nodding along should be forced to look at the reality of what they're nodding along to.
[^1]: Expressed, I might add, in the very language of Nazism and Moldbuggery.
[^2]: OK, the impact of the "population crisis" is overblown, but that's a very secondary point. It would not justify what that person wants no matter how real or how bad it was.
