I live to a quiet simple principle that works for many things:
Accept the things you can not change, to invest your energy in things you can change.

Where your parents are from, with which tradition and religion they raise you, what color of skin you have, what your sexual preference is are all things you have no influence on. Therefore there is no sense creating any conclusion because of ethnie, religion or sexual tendency.

No matter wht arguments to bring. Having a behaviour towards someone because of something this person can not change has no sense, since there is no opportunity to improve upon.
