I read your blog post in order to understand why you might be getting negative reactions. You are coming across off as combative and arrogant. It feels like you are quizzing people on details in order to show you know more than them.
I disagree. The questions are posed as challenges but are not charged, subjective, or overly pedantic. I also don't see where he's trying to show he knows more than they do in a self-serving way.
Some people choose to interpret any challenge as a personal attack. ¯\_(ツ)_/¯
