as a non-militant bicyclist I see this every day. People who insist on their right to ride where they are legally allowed to while at the same time being a nuisance. Yes, you can ride on the sidewalk, but it'd be really nice if you didn't. Yes, you can ride in the road, but do you really need to? In all cities where I've rode a bicycle, a tiny bit of planning and attention can usually result in routes that result in minimal opportunities for conflict.

You can certainly photograph street scenes without being a rude cunt.
