Why everyone hates Cowboys fans

On MSNBC, they're reading the names of the people who died in the tragic events of 9/11. One of the people who read the names, I do not know her know her name but these people were chosen because they had family that died. Instead of just staying that she loved her father (Who died in 9/11), she said that she hopes her father will help the Cowboys win tonight on week one. This is why everyone hates Cowboys fans. This was in the middle on the 10th anniversary of the biggest terrorist attack ever and she's hoping the cowboys win?! >:( I'll try to get the video.
