If you say "don't expect anyone who already cycles to support this" then my own case becomes relevant as a falsification of your theory. As would xThousand LCC members. None of which is a 'sample size of one' because we are not talking about a survey. Learn the meaning of 'sample size'.
But I didn't say that. I said "don't expect support from people already cycling if the most likely net effect is to make it worse for them."
I didn't say "from any of the people already cycling"
I didn't say "from people already cycling if the most likely net effect is to give them a safer and more pleasant route"
I said "don't expect support from people already cycling if the most likely net effect is to make it worse for them."
If you're not in this group of people then the fact that you support your own proposal is neither here nor there in respect to "falsification of my theory". You're a cyclist, you enjoy doing A, B, C whatever. That's great[*]. It doesn't mean there aren't other cyclists who prefer doing W, F, G and see your proposals as likely to make it more difficult or less pleasant for them to do so, and given the evident disdain in which you hold them it's hardly surprising that they don't trust you when you say that it'll all work out for them if they just stop trying to get in your way
[*] I mean that sincerely. I fall into both groups myself depending on what I'm doing, notwithstanding that taking my Christiana down the kerbed-off cycle track on Howland St was a dumb idea that I really won't ever be repeating. But you're exuding at least as much disrespect here as you're experiencing yourself and that's because you're treating the people you're talking to as kids and idiots
