Can you be on the left on one area, but on the right in another?

For example, being leftist when it comes to social issues like sexuality or religion, but be right winged when it comes to economy or relations to other countries or something like that.

Or the other way around.

In other words, is it possible to combine left and right wing beliefs and policies, rather than choosing only one or another? Have you ever met anyone like that?

Do we allways have to choose between the two? What if agree with both, or neither?
