Oh, and one other caution which all here might heed from time to time:

If you always assume the worst of intentions behind whatever someone else is saying to you, you may quite likely misconstrue what they're saying. Your own negative expectations of them thus become a self-fulfilling prophecy, one which rapidly leads you to conclusions such as:

He's a bigot!

He's a racist!

He's an idiot!

Etc....

(and then you may tell him that he (or she) is one of those things... and I guarantee he or she will be very offended when you do, and will probably counterattack immediately)

In any case, it does not lead to any kind of useful discussion, but it's great for starting a war or a personal vendetta, if that's what you want, and it seems to be exactly what some people want.
