I won't gossip and talk smack at work. Is that why my coworkers aren't nice to me?

I've worked there for 4 months and really don't want any part of the gossip and backstabbing. I'm a 28 year old woman who works with a bunch of bitter old ladies who constantly talk smack. I refuse to participate and try to keep to myself. Well now these ladies are seeming to turn on me and be rude. I'm sorry but I refuse to stoop to their level just to be accepted. I'm respectful and professional to everyone and don't see the purpose of gossip. Am I in the wrong for not going along with it just to be liked?
