No one is arguing for disagreeing just for the sake of disagreeing. We're arguing for disagreeing only when it's the best option to disagree. As opposed to conforming to a worse option only out of fear of being different.

"Wrong" is subjective, but a clear consequence of conformism (as I just described) that one might want to avoid. Is that it makes you more vulnerable to sacrificing your own interests for the interest of others. And more often than not, that means being vulnerable to scammers.

Now do it like everyone else, and make me a sandwich.
