While its understandable to not agree with certain practices and beliefs of certain ethnicities, hating the entire ethnic group because of disagreeing with certain beliefs is silly. And then many take it even further and just hate entire races.
race =/= ethnicity ethnicity =/= culture
it's not understandable to hate certain ethnicities, either. thinking ethnicity determines your "beliefs and practices" is just as crazy sounding.
I don't know if that's what you really meant or if you just misunderstand the terms you're using, so I'll give you the benefit of the doubt and reserve judgement.
You just said the same thing I said, lol.
But ethnic groups do share much of the same cultural beliefs. ---
