I don't care whether someone has a long rep bar or a short one. You can have a long rep bar, but still be wrong in a discussion.

Silly example maybe, but the one I can immediately come up with: say, if one person with a long rep bar says that currently in the manga Sasuke can defeat Naruto and one person with a short rep bar says that currently Naruto defeats Sasuke, I have to agree with the person with the short bar, because it's logical that at this point in the manga, Naruto is stronger than Sasuke.

So having a long rep bar doesn't automatically mean that everything that person says, is true. If I have a discussion with someone, I pay attention to the content of their posts, not whether or not they have a long or short rep bar or a low or high amount of post count.
