Do you only listen to people who think like you?

That's what many people do. They unfriend or unfollow anyone who disagrees with them and sometimes even block so their posts can't be seen by the enemy. (Like a child with fingers in ears and yelling so as not to hear anything disagreeable.)

I actually like exercising my brain with opposing thoughts. Now, Facebook is my "friends and family meeting room" but Twitter is my debate hall. I follow many people who do things I'm interested in, have similar political views, etc. but I also follow some who I fervently disagree with because I want to know what I'm disagreeing with and occasionally I find I agree with "the other side" on an issue.

For instance, along with many conservative and libertarian voices I also follow Obama, Hillary, Chelsea, Ellen, and other political interests. I love the freedom to listen to all, disagree or ignore freely, and generally soak up information.

Try it, you just might learn something.
