Should I show the real me or just make another account?

[female]

On Facebook, I have a lot of family and friends there. The thing is I love strange and unusual things, and I can be very harsh with photos, politics, anti abortion etc. I hold a lot of it back because my family and some friends are very judgmental and will gossip to everyone else and call me crazy. I added everyone not thinking, and now deleting them will make them ask questions lol. I do drink and I do cuss, and I do laugh at vulgar things, but again I play the sweet card online. Should I just show the real me and not care or make a new account that only my true friends will be on?
well...I hope they're ready for the real me lol.
*takes deep breath*
thanks for the answers
