When I was in school, I didn't like to argue. I didn't understand what the point of getting angry was. Until they switched me from religion class to ethics class.
There I learned to raise my hand. To express my opinion. To listen. And above all to understand that arguing sometimes is the only way to regain the status quo.
When the sack of shit gets full, it has to burst, to get back to normal.
Postscript:
I couldn't help looking for Stravinsky on YouTube to listen to him as I was reading your article. Thanks for mentioning him.
