They are-———tone deaf.
I think they are just lazy
It is easy to say you are for something, then to actually do the work.
Also convenience, it is more convenient to live in a house with heat and AC then to build a mud house out of mud and sticks and try heating it with a fire, oh wait fire would be bad as well releasing that evil carbon into the air, I mean a solar panel with electric baseboard heating, oh wait, the solar panel contains toxic chemicals and the baseboard heater is made of metal that requires fossil fuels to extract releasing carbon to manufacture.
That is why they are all hypocrites/lazy because they can’t live the life that they demand everyone else to live.
