Is flag burning, and rioting OK when your candidate doesn’t win but thuggish if done in response to cops shooting minority suspects or an unpopular war?

There was an election, the side that said the other was misogynistic, bigots, xenophobic, in short, they are not good people and more prone to violence, yet the ones making such a claim are in the streets “rioting, and burning flags”: https://www.thesun.co.uk/news/2147684/violence-erupts-across-the-us-as-pro-clinton-fans-riot-after-donald-trumps-shock-election-win/ (talk about Colin Kaepernick being wrong). Is it OK to riot when your candidate did not win and burn the US flag, but not for other causes? Does having your candidate not win gain one special exemption or privilege in doing these supposedly ”un-American” acts?
