Just ignore the fact that it makes things easier for other people. Setting up on the left side of the right-most lane makes it easier and safer for you. You are out of the way of the jerk who is going to try to squeeze past to make a right no matter what, and it removes any ambiguity about whether you're going straight or right. So there, just do it for your own selfish reasons that also just happen to make things safer, more efficient, and spread a little goodwill.
