What do you think of Lady Gaga - Judas?

i don't get why people are so mad at her for this song! I'm listening to it right now and i LOVE it. On my iPod i have 3 songs called Judas (Kelly Clarkson, Lady GaGa, Cage the Elephant) and they all have the same meaning. The song is about how she keeps falling in love with a guy who will break her heart. She's not mocking the bible she's making comparisons to a guy that will betray her and Judas who betrayed Jesus.
