>Because who decides when its not in the people best interest? Oh right, not the people since they clearly voted for them for a reason.

In Germany we have laws to ban parties that work against our constitution, exactly because of what happened in Weimar. The AfD is classified as confirmed right-wing extremist in five states. Starting a ban process is more than justified. The process is not arbitrary. Only the Bundestag, Bundesrat or government can apply, and the Constitutional Court decides after checking if the conditions are met. Also, just because a majority votes for something doesn’t make it right.
