The reason it is called "discrimination" is that it is a standard applied to members certain groups and not members of other groups. For example, even if you had been there said "it's a go" on the phone (and aparently, that's not what the lady in this case actually said), you most likely would not have arroused the FA's suspicions because you are white.

When white people are discriminated against, there is money there too (google "Ricci v. DeStefano" if you don't believe me). It just so happens that non-whites are discriminated against more than whites are in this country, so most plaintiffs in discrimination lawsuits are non-white.

Do you feel that you are discriminated against and can't make a case because you are white? Or are you upset that you aren't discriminated against, so you are unable to chance upon a profitable lawsuit? Or do you feel that whenever non-white people are wronged for any reason, they can sue and get money whereas whites can't? (If you believe this, it isn't really true at all as lawsuits are tossed out left and right because a nexus between a discriminatory motive and an adverse action cannot be established). Or do you mean something else by "I have nothing to go on, because I am a white European"?
