Gaga does go for shock value but that's her USP. She's a brand and she markets herself effectively but that subjects her to some very harsh critiscism. The meat outfit for example was one way of stating that people have no qualms about ripping her apart like a piece of meat. There've been lots of nasty and untrue rumours about her in the press - her 'being a hermaphrodite' being just one example. I personally think she's a good lyricist but don't like all of her music.
With the whole JW situation it probably doesn't help that she confesses in interviews that 'Poker Face' is a metaphor for her bi-sexual thoughts of being with women whilst doing it with a man.
The Society, and JWs in general, just love to vilify many aspects of pop culture. MJ, Madonna, Boy George, Marilyn Manson, Nirvana, KISS, Lou Reed, Frankie Goes to Hollywood, Ricky Martin, Public Enemy, Beastie Boys - were all denounced from the platform during my time as a JW as being evil, immoral, Worldly etc, etc. They claim they don't tell you what to think but boy do they try and influence every other aspect of your life!
