^So did I. I'm the most PC person around, but I saw it as just making fun of kung-fu movies and nothing more.
Is that the national past-time these days, being offended by everything?
There are people out there who apparently live to get offended and raise some trouble (mainly to get into the spotlight according to my opinion).
Chances are they didn't even get that they were making fun of/paying hommage to bad Kung Fu movies because they haven't seen any. But then again they may ignore it and decide to get offended just for the heck of it.
Sadly the producers didn't stand their ground and tell them to get offended somewhere else.
