The fact that you refuse to outright say "I am a Cowboys fan." Or something like that, plus the fact that you scoff at the prospect of being a "homer", tells me all I need to know about your loyalties.
There are three options to what you are.
1. You're a fan of another team.
2. You're a bandwagon fan and/or don't actually have a team, and you're one of those that are "just a fan of football." Bleh.
or the worst...
3. You're a bandwagon/hater Cowboys fan. In other words, you are a Cowboys 'fan', but anything and everything the team does, you hate. And then when we win, you celebrate like you're part of us for about four hours, and then continue with your relentless hating. Those types of fans I hate above all.
