Mate, you ever tried living on the edges of poverty? Clinging on to the cliff by the tips of your fingers only to have someone walk up to the cliff and instead of pulling you up they stomp on your hand?
I don't even know why the guy did it and I could be completely off base. It doesn't really matter because it's a hypothetical. I don't condone it but in that case I can understand it. To immediately jump to the conclusion there is extremism on "both ends" and both are equally bad when they can come from completely different places and motives is complete horseshit.
