This is fine and a good exercise (like a gratitude journal). The problem is that this is often used to tell people indirectly that they should stop with their political complaints, which may be well-founded. Like...

Like this?[1] I don’t know what extremist means here but there are real political problems out there, and some of the solutions are “extremist” (like e.g. some of the solutions to climate change).
Violence is less debatable and should be reserved for when it it truly necessary.
