Just stop. All you are accomplished is dissuading people from trying. Even if we fail, some of us would rather go out feeling good about ourselves knowing that we actually tried. If we succeed, I want to be on the right side of history. If you want to drive a canyonero through a drive through to buy a double cheeseburger on your way to the airport to fly somewhere for a shopping trip: please keep it to yourself.

Most people want action. I can cite more than one source.
Things are starting to turn around. Not as fast as we need to, but we are seeing change
Some of us are parents and have a reason to fight with all we have
If things get bad, our kids will actually want to have a relationship with us if we cared enough to try
Many things that help are economically better on the micro and macro scales
Doomers are the fossil fuel industry's best friend-- even more than the deniers are. If enough people succumb to it, they don't even have to pay lip service to the problem. Doomerism means you can continue to pollute and not even try.

Meh I just hate you folks and associate whatever I hear with bullshit doomerism rather than wanting to listen. I don't think you are as helpful as you think.
