Why Dallas Fans, Why?

I'm really mad right now.Recently, I was doing community service for my school. After we finished, the custodian asked me what grade I was in. I said "7th". Now it just so happens that I was wearing some of my redskins gear (as usual) , and he told me: "You won't be comin' back to this school next year if you keep wearing that sweater"! He was joking, of course. But it just reminds me of how much I hate the Dallas Cowboys!!! My school is crawling with Dallas fans! How can you say you're a Dallas fan, when you're born and raised in DC, and have probably never even been to Dallas. It's like saying; I dont want to be American, so I'll just be Canadian instead. That's what is wrong with this country. I just don't get it.Would someone tell me why this is? I feel like every time I walk down the hall, I hear "Redskins Suck" at least once. Give me a break please. So I wrote this post about the teams I hate:

First:
Teams that I Strongly Dislike
New York Giants
Philadelphia Eagles
North Carolina Tarheels

Second:
TEAMS THAT I TRUELY DESPISE

PUKE Blue Devils I hate these guys because they always seem to beat Maryland, like in 2001 when Maryland had a 10- point lead and Duke came back to win with 53 seconds left!!

Pittsburgh Penguins I actually just hate the city of Pittsburgh; and also because the Crosby-Ovechkin rivalry in last years' playoffs. The Caps have also played the Pens 8 times in the playoffs, and the Penguins have won 7 of 8.

and of course, the worst of them all,
THOSE DALLAS COWGIRLS!!!!!!! The Redskins have always hated the Cowboys!!!! Dallas always has the worst fans in any sport; and the worst thing about that, THEY ARE EVERYWHERE! They wont stop yapping about how "good" they are. I think they need to crawl back to their toilet bowl they call a stadium, and zip their mouths!! I also hate that ugly, stupid star on their helmet. They aren't, and don't deserve to be "America's team" (Kudos to George Allen for hating Dallas so much!)
See Ya!
