The number one reason is still don't have many friends around me is that the place where I grew up was(is) full of such racist and hateful people. I have never regrated not making a friend of them, in fact distancing myself from them is the biggest favor I have done for myself. I think you should never regrate your decisions. They question you should ask yourself if you are in doubt is "Do I want my kids to become like that person?." We all deserve the environment where we all are respected and loved for being Humans, not because we belong to some specific race or speak a certain language. Keep yourself clean with love!!
