It's about establishing credibility. You didn't respond with any data or interesting information. Your comments are simplistic, betraying a level of simplicity in your thinking.

I actually enjoy being correctly corrected, however being incorrectly 'corrected' is obviously annoying. Like being lectured by a haughty child, see Louis CK's bit of his daughter insisting they're called Pig Newtons.

Best of luck to you in life.
