why does homerism exist?

There are more anti-homers here. I define an anti-homer as a person who is eager to call someone a homer and refuses to look at the talent of the player mentioned. Even if the player is well regarded as one of the best in the country the anti-homer will still accuse someone of being a homer. Example is LaRon Landry, Glen Dorsey discussion.

Well LaRon Landry is obviously not a need since we just spent two second round picks on safeties. I think that is why people get called a homer for wanting him. If he were a CB, it would be all good.
