To tell the truth though, I am much more annoyed at people who pass on the right than those who fail to do so on the left.

Isn't that thre same thing?

No, a driver can see a car passing on the left more easily than one on the right, since you sit in the left side of the car. A left-lane slowpoke can slow you down, but at least you can see him. A right-lane passer risks an accident every time he does so, since he comes right out of one's blind spot, against the rules of the road.
