Sure. And none are universal. Cannibals don’t have any concerns about killing and eating people they don’t necessarily like. Especially if those people wander into their yard (for example).
The other side of the moral relativism coin is consequence.
Two men commit murder and only one of them is caught. The other gets away with it. There’s only a man made consequence for the one who gets caught.
You can’t have “universal morality” without an ultimate judge of character. Which, for primitive people, could be a compelling reason to invent a “supreme judge” (ie. God). Which is bullshit.
So, nothing is judged in a vacuum. Everything is weighed under the circumstances.
“Oh. You killed and ate your neighbor? Oh. You were hungry? Oh. Everyone else is doing it? Oh. It’s part of your culture? Okay. Well. Fine. As you were.”
Vs.
“Oh. You’re Jeffry Dahlmer? Oh. Well it’s the electric chair for you. Oh. You don’t feel any remorse? Oh. You’re a psychopath? Hmm. Well. Well … sorry. We’ve got “laws” against this.”
So, you’re substituting what you can and can’t get away with over a moral imperative to not cause suffering to other people.
You’re “brave” enough to beat a man to a pulp on your property because the United States of America allows it. But you won’t take your aggression out on someone in public areas.
Sounds like a) your moral standards need improving and b) you don’t live by your own moral standards.
You’re a coward. If you had any sense of right and wrong you’d pummel the man who threatened you regardless of whether or not the law allowed you to get away with it. You’d live by your own standards. Instead, you hide behind loopholes.
Rather than show compassion for living beings you a) repress your hatred in public spaces and b) unleash it in your own private property.
You are found wonting. That’s my judge of your character. And I am morally superior to you.
