To some extent we all do, and we are all human and all hypocrites. But, as the sages said " ."
We can, as a species, choose to kick ourselves in the balls *one less time* today than we did yesterday, and one less time than that tomorrow. We don't *have to* kick ourselves in the balls a thousand times a day, and doing it slightly less is still better, even if it's not as good as stopping entirely overnight.
That's why I drive an EV, use active and public transport a lot, turn lights off, use a green energy supplier, eat veggie more often than not, etc. Are there other aspects of my life where I could do more to decarbonise? Sure? Is it bad that I don't do them? Yes. Does that mean I shouldn't do the things I am doing to lower the carbon intensity of my life? No, Trailer Trash, it does not. Do my bad actions mean that we should ignore the systemic governance issues that make it harder for individuals to choose low-carbon intensity actions and easier to choose high-carbon intensity actions, like not building sidewalks in so many US conurbations? No, Trailer Trash, they do not. And do my bad actions mean that we should give Exxon's leadership, staff and owners a free pass to fuck up the planet as much as they wish. No, Trailer Trash, they do not.
None of this is very hard to understand if you just devote the tiniest amount of time to actively thinking rather than fucking about with pointless rhetorical gotchas.
