I don’t agree that the troll should be banned. He (she?) has maintained a civil tone, has not been abusive, hasn’t broken the rules, etc. I don’t think Charles wants to be depriving people of the ability to state their opinions, no matter how utterly stupid or ignorant they are or how much their stupidity or ignorance may annoy the rest of us.

As I see it, we have 2 choices: debunk or ignore.

Just my opinion, FWIW.
