You nailed that part of the etiquette.... right on the head. Although nobody is thrilled to get pasted particularly on open road (or path). But the "on your left" from the other cyclist is proper and appropriate. Your own hurt feelings... are you own business.

I haven't failed to enjoy even one bicycle ride... yet. I try leaving fear and ego at home. It seems to help. Anger is merely an emotional manifestation triggered by the fight or flight response. In most cases.... the anger doesn't even make sense. It would be my guess.... the fight or flight response.... pre-dates bicycle riding.
