not directed at you directly.
it doesn't though most of the time. culture divides along many lines and is tied in with geography, shared history, language, traditions exc.

it's right above if you want it.
Yea, maybe often was the wrong word, but it certainly does sometimes. I think the miscommunication here was that the way i said it could be interpreted as "Race causes different cultures" which is not at all what I meant. Culture develops along racial lines for a variety of reasons. A prominent example is the isolation of blacks in america through slavery, and afterwards by jim crow laws and racist sentiment by a large part of the population. Rejected and cut off from the majority culture, it was inevitable that a different culture would develop.
So, a culture develops down racial lines, but not because of "racial differences". It was because of events beyond control, starting with the proliferation of the slave trade.
In the above case the isolation was reinforced from the outside, but often it is self enforced as well. For example, the isolationist nature of the nation of Japan has lead to a very distinct japanese culture based around the japanese racial identity. None of this was caused by any difference in the "Japanese Race" but simply as a result of the decisions of governments, geographical factors, ect, ect..
An example of this originating from religion can be observed in india, from hindu class systems and national tensions.
Anyways, all that to say that culture does end up divided by race sometimes.
