You're using euphemisms.
"Won't embrace"= actively terrorizing
" difference is a deficiency "=completely inferior
" outcast "; stripped of human rights and dignity
You trying to water this shyt down
There's nothing watered down about it. When people dislike somebody for being different, the person that's actively hating sees the difference as a deficiency. They actively terrorize that person or group (bullying, but on a much larger, barbaric scale) and treat that person as an outcast.
When diversity isn't embraced and differences aren't accepted, that's when a problem exists. Racism is a symptom of that problem.
