How come people push political and or religious views

Why do people feel the need to try and get you to believe their personal views?

Recently, my adopted mother and sister cornered me in my mother's home into a conversation about Christianity. It was a conversation I didn't want to have, and I made it known.

Later, while visiting my Adopted mother at her home again, she got into a heated, one-sided rant on her side of her republic political views because I mentioned I didn't vote for the presidential election. Now, I'm told I'm letting Democrats win and Im inadvertently participating in socialism.
