I don't think that's true at all really about most people in the thread - it's just sabotaged a bit by those who are just... insanely extremist and either don't/won't see anything Martinez does as right/wrong (delete were applicable), as proved by a post by someone a few above, then people will do what is natural when it comes to an opinion of a thing; either shift for or against it based on evidence.
It's only those who have absolutely no interest in being wrong on the internet who will be... "davek-ey" about things. So about one in every hundred people. It's just that those people tend to shout the loudest and say the most stupid things that get a bigger counter-reaction.
