What kind of classes? Shooting? If so I’d say shooting won’t help much unless you have a community response to those threatening you. It just gives ammunition to those calling the American population dangerous, and trying to break them into groups so they can exploit hatred and fear. I believe that standing by all “groups” no matter what is what needs to happen. When someone tries to divide to conquer, the best answer I can see is avoiding any divides. The problem is it works on so many people, that about 30% of the country agrees that they have enemies in the country. Yet those people they think are enemies… Are no one they know, and would take as a friend if they were their neighbor.
