No. As I get older, I become wiser and calmer. At least I think I do (my wife would probably agree).

I constantly question myself and my beliefs and I always try to understand everything and everyone. I try to foster mutual understanding in real life by treating people around me equally and respectfully. That requires to be be able to see and understand many different perspectives.

Anyone can do something against increasing aggressions and radicalizations by simply leading by example.

I recommend to shut down or at least decrease social media usage. If you want to help people, go out. Be kind. Live an ordinary life. Vote for people with a honorable cause in mind. Try to avoid making generalizations and don't always judge too quickly. Support locals.

Make your life better by making other lifes better. Leave more good than bad behind you.

In the end, that's what you can do. And the more people are like that, the more people you can convince to be like that, the better this world becomes.
