As far as it not mattering how much CO2 is put into the air, yes, it does matter, because the Earth retains more of whatever radiant heat derived from the Sun. It retains more radiant heat from a cooler Sun as well as more of the radiant heat from a warmer Sun. Increased C02 retains increased amounts of radiant heat.
So, if we tripled the amount of C02 in the atmosphere and the Sun heats up, the increased C02 would aggravate the heating trend.
Conversely, if we tripled the amount of C02 in the atmosphere and the Sun cools down, the increased C02 would mitigate the heating trend.

I think you attributed my quote to someone else.
I don't disagree that CO2 is a greenhouse gas, or even has a part in global warming. What I'm trying to argue is that it's a tiny part of it, insignificant, really. The earth's climate changes without any detectable CO2 increase or decrease. Our records are not detailed enough to tell us the history of earth's climate down to the variation of 1C over a period of 30 years. Our records are of thousands of years at a time, with temperature variation of more than a few degrees celsius. Where ice core samples are spotty, "scientists" make up stuff to fill in the holes. The very foundation of this CO2 leading to global warming is shady.
It's like a business with an operating budget of $10,000 a day. Sure, switching all CRT to LCD will save power, but by how much? Does saving $3 a day really matter to a budget of $10,000? Power company can raise the rates and wipe out all the savings and then some. Or it can lower the rates and make up all the difference (using CRT) with leftovers.
