how do I stop giving a f*ck about my coworkers political ideas?

I don't talk about politics or religion at the workplace, yet there is a drama queen that loves just blurting out what she thinks to everyone around.

My way to go so far has been to ignore her, but sometimes I just want to yell at her how incoherent she is.

Then I'd be the one starting drama I guess...

I'm looking for advice to deal with these kind of people. I don't want to work listening to conspiracy theories.
