That's a great anecdote really. I think I tried exactly to play the angle of the human experience being very diverse. It obviously didn't work out. The story you tell is definitely one that shows different perspective in a relationship between people of different ages. There are also "famous couples" where the age difference is large (I wanted to discuss one where a female director is marrier to a 23 years younger actor, and they met on set when he was 18 - just to have one more scenario to discuss). Most importantly, I bet many people would have different answer to the question "what is the maximum age do you think a 18yo person should date", and probably this answer would change if talking about a man or a woman being 18yo. I think it's an interesting conversation questioning why you think a certain answer is the right one.

Now, I understand that people who want progress want to normalize discussions about phenomena that years ago wouldn't be acknowledged as much, like predatory behavior. However if the approach is purely dogmatic it is not a progress at all. Many people use a completely binary approach to define things that are much more complicated and nuanced. And as you say, this is then enforced via moderation, which further reinforces this dogmatic perspective for people who are forming an opinion.

Sorry for the long comment, but thanks a lot for the contribution. It was a nice reality check about the fact that it is an interesting topic to discuss with many nuances!
