I like this comment in your piece:

"For some reason, people on the Left believe they are incredibly susceptible to brainwashing, so they feel it is better not to listen to anything contrary"

Total liberalism, as you stated, is on a faith. AGW is a sort of religion to these people. They are loony.

Only an independent person would look at both sides of the story:
Left: Belief that mankind and a molecule, at 4 parts per hundred thousand, are responsible for accelerating the temperature, even though recent trends show otherwise.
Right: Data showing that the solar magnetosphere is at an all time low, as are sunspots, which correlate to William Herschel's data from 18th century. That CO2 levels have been higher in the past. That the earth is a dynamic planet and nothing stays constant, except for change.

This is what we are up against? This will be easier than shooting fish in plastic baggies.
