For example; you don't want to go all decked out as a rival fan to the Raiders or Eagles stadiums... could be a hazard to your health.
Violence isn't part of the mentality in Houston ... totally different atmosphere than you will find in other parts of the country. Only words are thrown at opponents at Reliant stadium... for now.
Texans don't generate much hate, being the new kids on the block and not being that big threat... for now.
Probably the most disliked team around the league is the Patriots because they are sitting at the top. With 32 teams and division rivalry, there is enough love/hate to go around to all the teams.
