>Just because someone has an idea doesn't mean I have to immediately agree with it or like it. Feel free to disagree with me on this, as it would prove my point.

Exactly. I am very happy to be proven wrong, given the arguments against my position are good. A lot of people shy away from criticizing ideas, thinking that a person will take it as a personal attack (gotta admit, I am guilty of this too, if I don't know the person well enough to assume they take criticism well).

When it is the fight for the best idea or solution, I don't care how wrong I am, I care about finding the "truth" aka the best solution given the situation. As long as the criticism is directed towards the idea and not the person, I am just as happy, regardless of whether my idea won or not (as long as the idea that won had better arguments for it).
