Agreed on seeing the extremes. If people can't be themselves here, where can they be? Some will claim "Oh, I'm just playing", but the reality is that the ugly person they are playing is the true them.
A major factor in all extremes are mentalities that fall outside the norm. We can all drift outside the norm as anyone who has lost their temper should know.
When a person is constantly outside the norm then it's a mental health issue since such behavior is detrimental to the person in the long run. In Matt/Wolverine's case, he's elderly. Nothing to be done there. In BP's case, she's young and very angry about something. Only she knows what it is and what the best long term solution should be regardless if it's "study harder", "get a divorce" or "flee to Australia".**
Agreed 100% about the lessons of history. Notice who pooh-poohs those lessons and those who preach them.
**Australia has always been my backup plan to answering Albert Camus's question. If I was willing to go that far, why not ditch everything and go have some fun first? What's the worst that could happen? I get killed? LOL
