I'm unsure if your response is to my ideas around helmet laws or something else? For context, I'm from Australia, where helmets are mandatory for all bike riders. Making them non-mandatory is a change that some think will increase cycling uptake.
Anyway, if it was to me, then
a) I'm a cyclist (over 6000km and 115,000 vertical meters this year. That's further than I drove).
b) Of course pedestrians deserve space. I'd prefer to change the laws to allow non-helmeted riding on separated bike paths only, but that would be useless as where I live most separated bike paths don't link up which means people must either ride on the road or (illegally) on the footpath to get between them. In a world where not everywhere is Copenhagen or Amsterdam I'd prefer to see children ride to school with their parents on footpaths than not ride. I'd prefer to see people who worry about helmet hair ride to work on footpaths and separated bike paths than not ride. Where I live both these things are currently illegal.
c) Yes. Riding on roads needs to be made safe. That does not preclude encouraging more diverse transport choices by making other changes too.
I find too many cycling advocates come from entrenched pro or anti-helmet positions and aren't prepared to look for compromises. That isn't helpful overall.
