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.

> 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.

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