I don't have an issue with having an issue with all existing countries. Why would I? It doesn't defend your point to say "oh so you hate when other people do it?" Yes! Obviously! I think military parades are bad, specifically because it glorifies violence and promotes a national identity around use of that violence to keep people insular. Like, if you dislike imperialism, you kinda should dislike nationalism, even when used in self-defense because it is a huge double-edged sword.

Real life is never so simple as to be either good or bad. Are things good in the country you live in?

Good and bad are comparators. Some places are better, some are worse. But the argument indicates that we should treat an unknown as better than a known, and that the red flags are just flags. I like the optimism, truly, but I would rather see evidence for it.
