a) monumentally callous, b) completely idiotic and c) a sadly all too common, stereotypical response.
Can you imagine someone saying "I'll support seatbelts when everyone stops drinking and driving". No, because it would be a stupid thing to think or say, just as it is to wish death and injury on large number of perfectly blameless cyclists because of the behavior of some.
There's a lot of terrible bike-riders (riding on the left side of the road around a blind corner...), but there are also a lot of terrible laws and signage. Don't delude yourself into believing that strict adherence to rules will solve the world's problems.
That said, some states are starting to address the stop sign/stop-light problem for bicyclists (well, sort of). Virginia, for example, lets cyclists (including motorcycles) treat stop lights as stop signs after a certain amount of time/cycles. I'm sure most cyclists would prefer they be treated like flashing yellow or flashing red lights (yield sign and stop sign equivalent, respectively), but we've got a ways to go before that can happen.
I think we'll need to start licensing street riding and overhaul traffic law to include bicycles on the road before things get much better.
For what it's worth, I don't even really bike that much these days and certainly encounter my share of idiotic bikers when driving/walking. But that doesn't mean I'm going to give in to blowhard legality tropes when it's clear that the real nuisance bikers are doing things that are so stupid (against traffic, on sidewalk, left turn from right lane, texting) that they don't care about even bodily harm. Meanwhile there are plenty of actions that are illegal yet affect nobody else that can be performed prudently and thoughtfully.
Also, any observably-broken traffic light can and should be treated as a stop sign. What else do you do, strictly follow the narrow part of the law that you've been told and patiently wait for the police to hold your hand?
