Regardless of my personal perspective, this is unfair. He stated a position which is not only widely disputed, but the dispute over which has an entire field of media and academics devoted to it, and which routinely splits the population roughly half and half (look at basically any election result in the western world). And he disagreed with your side. He's in the other 50% of the population from you.

To claim that being in the other 50% makes somebody "laughably wrong" or a "bully" is not a fair statement. (To say that there is "wide disagreement" is entirely reasonable, but to be fair one should also point out that there is also wide agreement)

This argument has been going on for centuries, with countless millions of people chipping in, without anybody really winning it. It is quite unlikely that this thread, or indeed this year, will be the place where somebody wins it. I think it is reasonable for PG to acknowledge this and bow out of the argument, and that's how I interpret what he's doing.

Life's too short to argue red vs blue.
