Somewhere in the ADD ridden post is the following (and something I believe as well):
Cheering a heel because you like them will actually hurt them. They are told to be a heel (aka to get booed), but when you cheer to show "Support" you're making them look bad. So if you really do love a heel, boo as loudly as you can. This is especially important for midcarders. The louder the reactions the more the people in the back will begin to think "Maybe we should push ___, he's been getting constant heat". Meanwhile though, if you hate a face, booing while isn't as good as cheering, does still help him. If you hate a face, give them the silent treatment. That will hurt them much more than booing.
