> Should I also avoid buying something with expedited delivery because it will be deliverd by an airplane? Should I stop flying for a vacation once a year? Should I stop inviting my parents to visit me, because they would come by plane Yes, obviously. > How can we be sure that flying is more immoral than other activities which produce CO2 (including driving, housing, electricity and so on)? Others have answered this in this thread and elsewhere repeatedly. > And again, even if in theory all people in the world will try to do only the "right" things, it will still work worse than carbon tax Again, false dichotomy. > Shaming is just counter-productive virtue signalling. Carbon tax is a rational and efficient way to solve CO2 emissions riddle This is just a nonsense divisive ans dismissive classification. It's called asking people not to do bad things and not doing bad things. Pretty simple.
