Well yeah, of course one should be 'ashamed' of being racist, but you'd be embarassed of the percieved racism viewed by others... interal psyche vs external.
Though like I said in other posts, I would be 'racist' enough to profile at airports with a negligible downside... but I wouldn't be 'racist' enough to TRUMP any ally action with the "a-rab card". When that card starts over-riding all kinds of facts... thats when it crosses into really hurtful 'racism' in my book.
Its just disgusting... go around and read a few UAE blogs. Be sure to browse back far enough before all this. They are stunned, they have no idea why their friend is treating them this way. The worst fallout from their end will take a few weeks while it gets play on all the "Al-" channels who "dissed" they were, simply because they are 'a-rabs'.
Racism...or just common sense, not much of which is apparent in the handling of airport security.
You're exactly right.
