He (jongaltsr), sounds like an agent provocateur to me.
New World Dictionary definition of “agent provocateur”: A person hired to join a political movement in order to incite its members to rebellion or illegal acts. And we’re too rational to fall for that game. We already know that passive resistance is far more effective than violence, because it doesn’t turn public opinion against you. That’s why our grandparents’ Civil Rights Movement was such an unstoppable juggernaut. They made their enemies look bad in front of the whole world.
Also known in various regions of these United States as ... a rooty toot.
