Bigotry and racism has to be isolated as human behavior that is sociopathic regardless from whence it comes. Segregation implies that there are those who are not worthy of
human compassion; those practicing segregation are dysfunctional people.

This sets aside religious, political or ideological considerations.

"Some" people behave in a mean manner regardless of what they profess to believe.

Oddly enough, some of this meanness becomes institutionalized when dysfunctional
people get together.

Look at what's going on today in our Capitalistic system and this behavior will come of no surprise to anyone.
