Politics & Social Media

I know the old saying about religion and politics, but I don't really understand why people are so tied to their politics. I understand religious views are close to your heart, they form part of our identity. I don't understand why we are so tied to our politics.

I also don't understand why people take things you share on Facebook to be your perfect view of the world. I know that sometimes I share things just because I think they are cute. It may not be that I completely agree with the sentiment, just find some aspect cute. It seems some of these strike a serious chord with some of the people who see my FB posts. Please people, think a bit.
