I'd say that anyone with that outlook isn't fit to live, much less live in a free society. For most of the world's history, such were either slaves or dead. And usually in that order. And as such, they were useless to those around them in the same predicament.
I will do my very best to slay those who threaten me or mine, and I will do so without mercy or remorse. Regardless of who they are.
Then there are my two liberal relatives (here in Texas) and the husband has a carry permit and keeps his gun on him. So, the wife asks if he would shoot someone who was attacking her. There was silence for a number of seconds, then he said, “If I shot someone, I would get in trouble.”
I was totally shocked he didn't answer immediately and shocked he wouldn't shoot. As I result, I think he carries that gun to be “macho”. This is Texas and he would not get in trouble if someone was attacking his wife.
I wouldn't want him next to me in an emergency situation because I couldn't depend on him to help defend the “fort” or us in it. I would be the one shooting for damn sure if someone attacked his wife who is my sister-in-law (even if she is a liberal to the left of Stalin).
