The frustrating thing about being human… is that some are not allowed to be human…. and everyone seems to own some biased opinion on some other group’s value.
Humans are resistant to updating their bias, even when they meet someone of that group that doesn’t fit their bias belief about that group.. they’d rather keep the bias and just say “well — that particular one is just ok “
They’d rather not update their thoughts or beliefs, despite being proven wrong on their own court. Its an obnoxious tendency.
