^There's no reason to have a distrust of anyone different from you. I'm Indian and I get along great with rural conservative whites, Mexicans and Nigerians in particular. I don't think it's about innately distrusting other cultures, it's more about finding which cultures are a good fit for who you are as a person. In my life, I've found that there are some categories of people that by and large I just do not gel with. I've never had friends from those groups and my interactions with them have largely been hostile/negative. Conversely there are other Indian people I know who get along great with people from those groups.
It's about where you fit in IMO, not immediately distrusting people because of their background.
