Sounds to me, this is a perfect time to invoke DEFCON 1's Rule Of Thumb 1 and Rule of Thumb 2.
Post-count has so little to do with rules knowledge you may as well say, "Anyone with more peanut butter on their scalp during a full moon at high tide in August," and use that as the definition of who to listen to about rules.1 - If you find yourself arguing a 4E rule with someone, take a look at both your and your discussion partner's Post count. If his/her count is more than 1000 above yours... assume that you are probably incorrect and should really pay closer attention to their argument and the sources they present to prove it.
2 - If you find yourself arguing a 4E rule, take a look at how many people are on both sides of the argument. If there are five times as many people on one side as the other... assume that the lower side is probably incorrect.
And the majority of people arguing a point on one side does not make them all automatically right, either. It just means they're all sheeple who like to congregate around whoever seems to be winning the argument so that they look smart and can hang with the 'in' crowd.
