Look Jim, the point I'm trying to make is not that others speed and I don't.
Rather, it's that the speeder has to accept the fact that they are the problem in traffic, not the others. Road rage due to slower traffic is more often than not due to the speeder's impatience--and their apparent lack of ability to slow down and be patient--rather than somone who happens to be driving legally at the speed limit in the left lane.
So if I do speed, and then I encounter slower traffic, it isn't "in the way". I am the one to blame, for exceeding the legal speed, not the legal traffic just because it may be slower than I am driving. And even in the leftmost lane, if the driver at whatever speed is actually actively pbutting traffic, I don't consider them an LLB.
But regardless of the speed of the car in front of me--whether below, at, or above the speed limit--if I can't find an opportunity to safely pbutt on the right as necessary, and the vehicle isn't merging right, the answer is clear: I still need to slow down in order to maintain a safe following distance. And that either involves letting off the accelerator pedal or even using moderate braking--both of which are trivially easy to do in order to reduce speed as traffic conditions require.
