Gentlemen, this is getting rediculous and plain depressing. A man should be judged by his fruit (what he conveys about himself towards you) not what "you" may think of him, his colour, nationality or religion. Rid yourselves of this stupid stereotypes, please!
I trained with a Lebanese chap, again more interested in getting up to FL100 rather than studying (or even thinking). Had a nasty habit of spending money and lots of it, without knowing when and where. He was a bit of a nutter too, got involved in incredibly stupid things (that could've been avoided had he completed the checklist's) - What! should I be suspicious of him too?
