Chinese and Indians fall into "model minority" stereotypes, which have their own set of evils (you are X so you must be good at Y is it's own kind of dehumanization). So someone making a gut call might have underlying prejudices for Asians and against blacks.
In other words, when is the last time a white person has crossed the street to avoid a Chinese/Indian person walking towards them. Ask a black guy when the last time that happened.
I think there are also many cultural differences at play, as well as people's perceptions of those cultural differences.
Startups take their own kind of crazy, and it really helps to be surrounded by people that tell you its ok to be crazy or are at least as crazy as you. And if you are going to be around crazy people, you will probably want to know that they are the same kind of cazy :) Being from different cultures (or assuming you are) will make it harder to sense this.
