I'd say the US has a problem with ignorance, and cite you as an example. Too many Americans die due to dumb asses like you that are armed. We can see from your posts that you a complete coward lacking critical thinking skills, and you are precisely the kind of guy who shows up on the news these days. And yes, some of you guys end up on the police force making the rest of the force look bad and further exasperating the problems.
It starts with small steps. For example, banning racist content on this forum. Two, denouncing guys like you who deliberately stir up trouble demonizing others that don't look like them. Three, ban high powered weapons that have no business being available to citizens.
