Yea, I'll never understand the 'hate' side of things - music, sports, celebrities of many kinds..... makes no sense hating people we don't even know!
As for Swift "ruining the NFL" as I read some days, I just shake my head and wonder how we've gotten here. it's not like she has a camera crew following her around to steal the show - she's in a suite with friends and family cheering on a team and her boyfriend. With her incredible notoriety, It might be the closest thing to a normal event she gets to attend and enjoy!
