The short version: The ******** were the last team to integrate. George Marshall heavily opposed desegregation and it took the Kennedy Administration threatening potential action against him before he finally decided to cave in. Being that at the time this occurred, there were quite a few African American's in the area, they naturally rooted for the team the Skins hated the most which were the Cowboys.
Judging from your post you really hate Dallas
.
If you are being serious, I have no problems sharing how I became a Cowboys fan.
And if you re-read my post, I never said there was an equal amount of merchandise around town. I said on those off brand stands around the malls there is a ton. When I first visited D.C. back in 2002, I nearly died after seeing all those "D.C. stands for Dallas Cowboys" t shirts.
That ether must burn the souls of ******** fans in D.C....
