I've answered him many times. Did you just not know that, or were you dishonestly ignoring his history of cowardly trolling here?
(And do you especially like the way he blames TheJews for all kinds of things?)
Your side has been faceplanting at the science since the 1970s. Your side has been predicting a new ice age for 50 years running now. You've all been as wrong as it's possible to be. Thus, you're considered to be political hacks and clowns.
In contrast, our side was predicting warming in the 1970s. We've gotten everything right, so we have credibility. If you want the same sort of credibilty, you have to stop failing at every single thing, and do some actual good science. Complaining about how unfair it is that failure doesn't bring credibility will not bring you credibility. There is no affirmative action for denier garbage psuedoscience.
If you think he makes a good argument, summarize what you think his good points are, in your own words, and I'll address it.
That is, if you're not just trolling, and you're not too scared to debate me.
