Tbh topics about sexual stuff, especially fetishes and paraphilias, are really hard to talk about with average people because it requires having prior knowledge of how they actually function, which the average person simply does not have. In my SJW phase, I had zero knowledge about what those terms even were or how they worked. For example, I did not know that people have "kinks" or fetishes in clusters. Someone with a fetish for choking someone isn't going to stop there, they will also typically have other violent fetishes like hitting, spitting, cutting, etc. too.
I don't want to fight you on this and you might even agree with me here, but that's not something you didn't know, you just unlearned that. Every child knows that behavior patterns cluster, that's survival instinct - you just unlearned a fundamental observation:
It's not that people aren't privy to the ins and outs of - in this example - sexuality and how it works, they are lying to your face about it, because everybody has a pony in the race and in your example it was saying the right thing to virtue signal (just taking you up on that SJW thing there).
Even if you do manage to stop and realize that "Huh, isn't it weird how people who like choking also seem to really like hitting and spitting too?", you likely won't connect the dots as to why that is and why it should be a cause for concern.
We don't know why, that's the problem.
We might discuss ideas as to why, but that naive observation alone is the point at which discussion often stops and the lies and self delusion begin, people will contest the observation - gas light everyone, before it even starts - they know what they are doing.
Going with that example, my guess:
Everyone who laughed at tom and jerry as a child has a working theory as to why.
Lay people know that someone who indulges his sadistic impulses at the cost of some "sucker" who takes it without resistance, will try and go further and further.
But we act as if we need to consult experts on the most simple things now.
It's not only the deference to authority, one often sees,
people aslo stopped discussing ideas about a shared perception of reality in favor of discussing the perception itself.
That's one key issue. Not only are moral axioms highly divergent, people become more and more isolated in their perception of reality, because they now can get turbo brainwormed in facebook boomer groups or online coordinated, interest filtered irl echo chambers. Same with dating apps.
The only shared values are money and vague 9-5 work ethic memes, the rest is diversified niche catering, placating people by isolating them into little, personalized mindscapes - the price is the ability to have fundamental meetings of minds.
