PHILADELPHIA – If you've been online lately, you've seen the criticism. Katy Perry is a spoiled brat. She is too thin and can't dance. Katy Perry brought a set list to space and her “143” album is a flop.

Can we maybe enlist the "Leave Britney alone!" guy at this point and swap in Perry's name?

Seriously, why all the hate? What has Perry done to provoke so much agitation and scorn?

So her “Woman’s World” video didn’t land with the irony she intended. So she had dinner with the former Canadian prime minister after her breakup with Orlando Bloom. So she toes the line between bold and bizarre.

If Perry were the monster so many internet trolls profess her to be, she probably wouldn't be selling out arenas – such as Wells Fargo Center in Philadelphia Aug. 9 – on her Lifetimes Tour.
