I hate politics

Hi! I'm a 20 years old girl, and I feel myself in fault because I have no interest in politics or any other topics outside of my special interest.

Every time other adults like my mother and my teachers make me feel less because I don't have any interest in that.

Any other felt like that? Am I obbligated to being interested in that? (I tried but every time I fails and other people make me feel more stupid if I talk about politics) How can I become more interested in that?
