You're right, bicycles do belong on the street -- it's actually safer for them there (most accidents are at intersections, and the closer you are to the middle of the road, the more visible you are).
However, far worse than pedestrian ragers are car ragers. There's something about being isolated in a bubble that turns ordinary people into ragers. And some of these car ragers believe that bicycles belong on sidewalks and deliberately endanger bicyclist lives to force them onto the sidewalk.
There's no easy solution, but one is simply more bicyclists, making bicyclists a common site on roads.
