Why don't you explain any civil war in literally any country? They faced a moral clash as well. My point in this post was not to talk about slavery but why morals have gone away. You seem like you disagree with what I say, but I feel like were all becoming less American and we're not distinctive anymore like, let's say, the Japanese are with their manners. What are Americans? Christians. The great compromise allowed slavery, none of those who disagreed with it liked it, but it stayed until 1865.
Perhaps to answer your question then, the best times for America would be the 1700's. I can list any year and anyone will say it has some negative thing in it, but what year does not? In the 1700's people mostly have their heads screwed on tight but no year is perfect. I prefer rules, morals, customs, where the men dressed and so did the ladies, where manners were a thing, etc. Today that is all gone. It's bland and boring. Sure, everyone is equal, but that's just that... Equal, but not different and distinctive. Causal clothes for example is what everyone wears and it's so boring. I wear a suit everywhere like I'm about to get buried. I like morals, I like my Bible, I like rules. I like being different like people should be. Society should be distinctive and how they act, not progressive in how everyone thinks. There's a difference. In the 1700's people were distinctive. In 2019 people are progressive. One is quite annoying and one is quite elegant.
