Is that remark aimed at anyone by chance?
To accept and manage risk (and you quite rightly point out there is risk in all walks of life), you have to be aware of it. Riding defensively, primary position, etc etc etc is all about reducing your exposure to risk.
I guess a lot depends on your definition of 'dangerous' but, for me, I say cycling is dangerous in that I am at risk of death and serious injury. That it thankfully hasn't killed me doesn't mean it isn't dangerous. That the stats say it's not as dangerous as, say, walking (because there are fewer deaths) doesn't mean cycling itself isn't dangerous.
Risk doesn't stop me from cycling but it does make we aware of the dangers. Isn't that a wiser approach than taking a no risk approach?
