It bears mentioning that this is a highly vocal/visible, tiny minority. They serve to poison the well. Folks on the left are inclined to point at this bullshit and call folks on the right idiots; the vast majority of folks on the right are like "I'd never do that."
On the other hand, this small minority is numerous enough that every Prius owner I've known in Texas complains about this. In their frustration, it's easy to see why they'd paint with a broad brush.
They say that, but they also don't seem to be willing to call it out. When presented with the electoral equivalent of coal rolling, they clicked "yes", enthusiastically.
There appears to be an asymmetry: both parties have their extremes, but one party marginalizes theirs and the other celebrates it.
However, these people are using car emissions as weak chemical weapons. They intentionally crank up pollution to harm people. If a single car without emission controls is this bad. The problem becomes visible and the conclusion becomes obvious: There is no way millions of ICE cars with emission controls are good for me.
