I do know history. That’s why I asked with very specific examples of time periods. I know the point of the comment is to be on the offensive because you don’t actually have an answer, but know that I see you.
I know every civilization falls, because that’s a tautology. It has to be the case. That does not mean anything towards your point. The US must fall eventually, even if that’s just the heat death of the universe. Again, admitting this doesn’t provide any reason for why.
Which civilization was the greatest, in your opinion, and at what time? I can promise you they were performing acts both of us would agree were horrible at that moment. “The past” isn’t the best time just because we are past it, and we aren’t necessarily in decline. That can only be decided in the distant future, and it won’t be because of drag shows. It’ll be because of actual policies.
