They're like brutalism haters in that while I personally enjoy it, they're not wrong. There's very bad examples of it. But also anyone who gets into hating it a lot seems entirely incapable of producing any evidence for it being so. They're like truffle pigs for getting it wrong. What the Habitat 67 is to architectural aesthetics is "guy getting run over by a car cutting the corner standing still at a red light" is to active transport
Hating cyclists from carbrain perspective is always dumb but it can be reasonable from a pedestrian perspective. Those newer electric bicycles with fully vestigial pedals do go way the fuck too fast down shared pedestrian/cyclist paths in my city. It's technically already illegal for them to be on those paths but it is not enforced.
One time my partner's manager at work went on a peak boomerific tirade about how cyclists cause more emissions than cars due to the cars that pile up behind them unable to pass
I wish there was enough cyclists on the road to keep the chariots permanently unable to pass
