basic human decency, listen, I agree with you. But this is an assumption that you’re making. There is a percentage of the population (some think up to 4%) that are absolute sociopaths. We also have to live with them. Even if they would be ok living without us.
It isn’t about a wish list. People will always be people. Until we somehow cure sociopathy or whatever drives people to be ignorant and cruel (my opinion on conservatives is they are probably borderline sociopaths).
Our options are to work with these people or go to war and exterminate them.
I don’t see how you holding everyone to your standard of morality (even if I wholeheartedly agree with you) is of any use in this. We HAVE to ALL live with each other and do the best we can. Aiming for your absolute unyielding moral compass doesn’t help.
