As a more generous interpretation of ZeroGravitas' comment: As the bird-and-windmill example shows, those people "worrying" are thought of as denying the fundamental viability of carbon taxes and only use the poor as a popular argument. Worrying about progressive taxation effects is of course very important, but then again also pretty easy to mitigate. And considering the fact that the parties propagating carbon taxes are mostly also the parties caring about the poor, I'm not very worried that the poor will be willingly outpriced of their mobility needs here. After all, that new tax makes the very resources available that would be needed to mitigate the unequal burden it would create.
There's a fairly large contingent in tech that leans libertarian while also recognizing the impending climate disaster. A climate tax is simply accounting for the externalities of your actions.
I wouldn't at all assume that somebody on this site advocating for a carbon tax would take care to not make it regressive, and I think parent's lumping it in with bird strikes (a total red herring considering nobody is talking about banning cats or glass windows) and lithium ion mining (a failure to account for opportunity cost) is pretty conclusive.
Yes I am not from the US and thus I may be biased by the local political spectrum. Libertarianism is something uniquely US-American, I think. We do have bird strike protesters, though, and they pretty much all are from the right.
