I think that we are entering the final days / years, personally. Think about how far advanced the Roman Empire seemed (Indoor plumbing as an example) until they became relaxed, full of themselves, praised athletes more than teachers / priests, became "tolerant" of an "anything goes so long as you are happy" society.
To me, true tolerance is when I say "I disagree with you, and I don't support your choice to (whatever). I do still love you, but if you want to be in my house, respect my opinions and rules."
What has me worried about our future is, no matter how loving and respectfully I say that, more times than not I am told that I am not being tolerant and that I am trying to judge.
Tolerance is becoming code for "let me keep do what I want and don't say anything - even if it steps on your rights a little bit".
I just don't but it.
