>How many people here avoid flying out of principle?

I'm not sure what you're expecting, but surely it's lots?

Yes, I didn't really expect an answer as nobody has those numbers. It was just rhetorical.

Many have drastically reduced it, I think you assume too much environmental cynicism.

Yes, it is quite possible that I am a bit jaded. I just get tired being lectured to on that - not by you or the OP, just randos IRL, who love flying all over the world on vacation, while driving a prius or tesla.

I thought the subject was cars right now. I see the point of bringing up something for a larger perspective, but this here is just whataboutism. With this "argument" it's useless to talk about any source of pollution - because there always is another one. Also, using a different car is very easy, it does not compare to not flying, so the comparison is more than just a little flawed to begin with.

My point was about being principled not whataboutism. Of the people telling others to not drive cars, how many people are avoiding flying for non-essential travel? Its easy to tell others to sacrifice, and I'm sure that everyone has at-least one cause they care about.

What if one wants to drive a gas guzzler, but avoid airline travel? :)
