I recently found out that "to request" doesn't mean merely to ask for something, but to ask politely. I've always thought of a request as a more formal way of expressing a demand, and if someone were to say to me, "I request that you open the door for me," I would certainly not consider that polite. Does anyone else feel this way?
I've never associated politeness as being inherent in the meaning of 'to request', and I don't think that's the case at all.
I agree that 'I request you open the door for me' does not sound polite, but that's nothing to do with the word 'request' per se. If you said 'I'm asking you to open the door...', that sounds equally demanding and impolite if you like. The 'impoliteness' comes from the absence of the word 'please'.
