Sure in a hypothetical alternate reality where the only way to defeat evil is to shoot it. Unfortunately we live in the real world and it just means more dead people.
Maybe I’m feeling cornered, vulnerable, angry, as is often the case with these things. But how do you suggest we protect ourselves and our allies from an evil that strengthens itself off of your sickness, your hunger, your homelessness, and has absolutely no qualms about meeting you with violence and coming up with an excuse later?
I would not suggest purchasing a gun if you are feeling cornered, vulnerable, and angry. Fear is the mind killer.
I would suggest reaching out to others, talking, getting political, and organizing.
Bringing a good argument to a gunfight is unfortunately not a winning strategy. When the fascists have no qualms shooting you simply for being yourself, no amount of peaceful organizing is going to stop them. Peaceful protests and organizing only work because they have the implicit threat of violence if the demands are not met.
When diplomacy fails, you’re left with two choices:
Violence or giving up.
Diplomacy is proving to be ineffective. That leaves only the two above options.
Trumpers killed exactly zero gays today. Meanwhile over one hundred Americans died of gun violence including a couple of children.
This is the difference between your fantasy and my reality.
