"It's not malice, it's not racism, it's just really uncomfortable."
Being "uncomfortable" is one kind of feelings racism stems from, being uncomfortable around people you don't really understand. Not saying your feelings are bad or you are bad, just that people are emotional rather than logical beings. There were definitely some subset of racists who were racists not because they logically analysed the science of race, concluded that their own race was "superior", but rather, they felt uncomfortable being around those they assume is from a particular race. There were establishments that were "whites-only", I assume it's because the owners were afraid its patrons would be uncomfortable eating with "blacks".
While I agree with what you say, I wouldn't draw the same parallel. Its more along the lines of ending a phone call when the other person is in a low-service area. The point of talking is to communicate, and communication only happens when the people understand each other.
I get the same thing with my sometimes spotty grasp on the German language. While, for the most part, I can be understood just fine from Berlin to Munich, eventually people get frustrated and ask me to switch to English. Not because I'm American, but because I'm terrible at speaking German. It just takes too long for me to understand them or to make myself understood.
So I agree that racism sometimes stems from being uncomfortable around people who are different, but I wouldn't go as far as to say being uncomfortable around people who are different is necessarily similar to being racist.
I get this all the time with russian, I can understand basically all russian but my ability to speak it, sucks. So Russians will tell me to just say it in English bec most have a better grasp of English than I have of Russian, they'll speak to me in Russian, and I to them in English.
About the Phone thing: When I get someone from South East Asia for customer support, I ask them to speak phonetically in the most courteous way possible, this was after yelling at a few reps who just didn't understand a word I was saying, nor I them. I felt there had to be a better way than to berate someone for just trying to do his job (somehow the women were easier to understand, probably just the luck of the draw). Anyway I highly recommend it to everyone who complains about bad customer rep phone calls, learn the Phonetic Alphabet (I have a copy taped to my wall for easy access) (Alpha, Bravo, Charlie, Delta, Echo, etc). It may be a little slower but if they don't like it they'll just transfer you to their supervisor or to someone with a better grasp and no one feels bad at the end of the call.
As far as I know racism stems from one race thinking they're more human than the other, which occurs, I think, due to the perception of differences in intelligence when the perceived inferior race is trying to communicate, in a sub-optimal way, to the perceived superior race, and being constantly made fun off in the process.
I imagine a typical racist comment in 18th century America: "There's no point telling the slave, he's not gonna understand anyway.".
It also stems from potential gain, you only have to look to former colonies to see this. It's much harder to subjugate a people if you view them as equals.
