The rules are simple.
1) Always stay as far left as safely possible (i.e. dont hop into the left lane for about two seconds if you're just going to overtake again).
2) Pull into the next lane on your right to overtake. If you're going quicker than the car in the adjacent left lane and some gimp comes speeding up behind you flashing their lights. Ignore them and follow rule 1 as soon as safely possible.
In my mind, there is no arguement to be had here.
