Recognizing default responses

Growing up, I've always felt grateful because I was blessed with very open-minded parents who taught me to be respectful of others' opinions. But after reading through my On The Media posts, I recognized that I too have my own default responses that I lean toward. I think some of those responses come from the community I grew up in and the people I surround myself with.
For example, I've realized that during this semester, especially with the presidential election, I've had a prejudice toward Donald Trump and his supporters that I allowed myself to not hear any information or point-of-view from his side of things. Now that he's our President-elect, I'm realizing how dangerous that was for me to have that default response. Now I find myself going back and trying to make myself listen to those who support him to learn exactly why they support him. No matter how much my parents taught me to be open-minded in my thinking, I have learned my own set of rules and default responses for how I think. I've noticed that what I wrote about in my On the Media posts mostly leaned toward my more liberal views. I didn't really address the other side of issues, which I find to be important. But when you have your own bias on issues, you don't really notice when it's written down.
