Hey guys,
This is based on my experience with both groups. I have done Pick Up Artistry with both groups. I would add that there's of course exceptions to these observations.
Asians: I feel Asian-Americans tend to be very cliquey. The groups I was a part of then to be hierarchical as well. Also it seems a lot of them kept "secrets." For instance, the "higher ups" would not share some information with those lower in ranks. It seemed everyone was competing with each other.
Africans: I had good experiences. The one's I met would go and game in a group making it easy if your friend was more skilled than you then you could pull together. Also most people would "pump up" the group to make sure everyone felt great about improving their skills.
