If you are looking at the facts and deciding they best support climate change, that’s not racist. Not at all. I suppose there might be racist reasons for believing in it, and certainly proposed responses might be tainted by racism, but a blanket statement that mere belief is itself racist is ridiculous.
The unpatriotic charge is also a bit suspect. Again, why you believe, and your proposed response, may well be unpatriotic. But mere belief, what?
