Why is it a bizarre stance? Take the word "valid" out of your comment and you will see the value of at least understanding why extremist groups pop up. They may not be valid, but understanding their origins, roots, grievances, etc. allows us to formulate potential interventions that could take place before having to deal with armed criminals in a life-threatening manner.

It's a bizarre stance because justifying violent extremism creates more violent extremism, which endangers us all. Choosing this method of political activity should (and in my opinion does) automatically invalidate whatever political arguments you have. If you have legitimate political grievances, bring them to legitimate political arenas.

Note how my philosophy still allows you to address origins, roots, grievances, etc. while also preventing the formation of violent militias because people won't listen to them or take them seriously. Yours forces us to take violent extremists seriously, even when their underlying concerns might not be worthy of consideration. Which is what violent extremists want.
