I am a cyclist, although (at 67) I don't ride as much as I used to do. I'm also in the US, so please read right for left if you find this difficult to follow.

I ride on the right, but I don't ride in the glass and debris-filled gutter. I stop for signals, don't ride on the sidewalk/pavement and generally use turn signals. I clip on front and rear lights on the (rare) occasions when I'm going to be out after dark. If a car passes me on the road, I feel no guilt by then passing him safely on his right when he stops at a signal - what would you prefer? Should I stop at the end of the line of stopped vehicles? I look to see if the car stopped next to me is signaling for a turn, and either wait until he has done so or I go ahead if he signals me to do so.

I think that, if I ever visit the UK, I will leave my bike home. Not only because there are apparently so many idiot drivers there but also because I really don't recognize the fraternity of cyclists in the behavior you are all describing.
