Violence is stupid. In some situations, it's just an output for one's rage. In other situations, it's a battle of who is best equipped (hardware + intelligence). Neither of these address the core of the disagreement. Violence only beats the loser into submission. It does not change their stance on the matter.
Negotiation, on the other hand, ideally, at least gives all parties some gains and losses. It may not be the end of the matter but it's generally a positive step and should promote some degree of respect.
Maybe we never had it, but I think we've largely lost the ability to be respectful and empathetic to others. Even though we find to be of the greatest evil, I think, should be given some initial respect to try to understand the emotional reality of their intent.
I won't write it out, but imagine the worse crime an adult male could do to someone. Something so revolting that the only "logical" recourse is violence. This is an emotional response that does not address the problems that brought this person to such an evil act. By ignoring the problem and beating the person down, we are not able to understand how they got to this place or how we can recognize this path in others. This is a brief example for the sake of time. If you look at something like genocide, I think the process does scale up but too complex to write out for now.
I condone empathy for all because we all as a species benefit from it.
Edit: on second thought - violence used to preserve life may generally be acceptable.
Not to discount this helpful and important information but, for the people you're trying to direct this to, I genuinely don't think it matters. This administration has thrown out habeas corpus and due process. And they have done this because a substantial portion of the population voted in favor of kicking people out who don't look like them. It's called Nationalism. And with that comes Fascism.
The core identity of the United States is disintegrating by public opinion. The one thing that brought pride to generations of Americans is being driven out and replaced with the same reasons people had left other countries in favor of the US. It's gut-wrenching.
So, yeah, get your papers but don't let it fool you into believing it protects you.
Hah - also funny to look at "only about 50% of US citizens have a passport" to understand exactly why we've turned into Nationalists.
