To people of ethnic minorities (or any other minority) who "pass" as the majority, how does this affect your life?

I am referring to any person of a minority populace, be it ethnic or any other (such as sexual orientation), who “passes” as a member of the majority populace to do such things as have an easier time getting jobs or housing… or just to avoid the looks and attitude directed at whatever minority group you are in.

A couple of examples would be a pale member of a normally dark skinned ethnicity passing as white or a gay person saying that they are straight when asked their orientation. If for some other reason, please let me know.

This could be “passing” full time or part time.

My specific question: how does this affect your self image, interpersonal relationships, relationships with your family, opinion of your ethnicity, etc?
