I hate cyclists! Not you, I mean other cyclists
Can you use this to challenge (if you can be bothered)? We get something similar on immigration from the “I’m not racist but..” types who will happily rant about immigration on facebook, forgetting that my partner, included in the conversations, is an immigrant herself. It can be fun challenging the “oh no, we don’t mean you” brigade when they try and wriggle out of admitting the reality, which is generally that they mean darker skinned immigrants..
In a cycling context, a resonse that they don’t mean all cyclists, just the red-light-jumping pavement-riding ones, gives the opportunity to respond with “me too, they give the majority of law-abiding cyclists a bad name” which might plant a seed in their thick skulls that cyclists are individuals?
