You can of course have your own morale, but there is nothing objective. I cannot personally relate to that either, but I also acknowledge that this is purely cultural and therefore relative and possibly temporary. I find the arguments that by definition label it as wrong or worse grooming to be moralistic and - to some extent - bigoted. Even if directed towards a person that probably is a bigot himself etc.
That’s about as far as I’m willing to take this conversation. Advocating for cultural relativism to defend a 42-year-old dating a highschooler and then calling me bigoted for not accepting it…I mean that has to be the bravest take I’ve seen in a long time. Indefensible, but brave.
By the way, I am an American and this guy lives in my society and culture. Please don’t be an intolerant bigot - apparently that falls under your definition, which is bizarre.
