What’s this sub supposed to be about then?

Hey guys. A couple of days back I posted on here the absurdity of someone two years older than someone else having control or authority over someone and people actually came on to defend the argument and downvoting me. Thought this sub was about how the way people are viewed by their age is bullshit. Naturally I assumed people here of all subs would get my point but they didn't. Using laws of certain country's only to try to rebuke my point. On a typical sub sadly I'd expect it but this sub isn't usually like that. It IS horeshit that people two years apart can get split socially. And it certainly doesent mean you hold power and authority over them. So what actually is this sub for then? Because when I defend youth rights suddenly this sub argues against my case.
