It feels off because the author is a conservative. But he's rational and well-spoken. We should be able to welcome him with "I disagree with you but I will listen to your arguments. Sometimes they will be persuasive and change my mind and other times they will help me to strengthen my own arguments against your position".

But his arguments also attract the wackos and are used as justifications by them. Therefore we have an urge or desire to just shut him down justified by "don't feed the trolls".
