Just to clear up any confusion - you can understand violence and racism, but not littering?
And if I do understand correctly, maybe it’s because that’s how their parents were, so they honestly just don’t think about it. My parents were the complete opposite so I abhor it, but I’ve known folks who don’t think twice. We’re still friends, I just try to gently remind them.
I do not have any racist or violent actual friends friends though. Like, I don’t actively pursue their company.
