Recognize a common root feeling within an adversary.
Read a post on social media or a news article that is in opposition to your worldviews.
Read it twice. The first time, place awareness on what reactions you are having personally while reading. Maybe there is a voice in your head that is getting fearful or judgemental or angry.
Now, take 3 deep breaths and re-read that post again. This time approach it with humility. Go beyond the words of what someone is saying. Try to determine if there is a common human feeling that is driving the person who wrote it.
Could it be that the person feels out of control or insecure or afraid or that they have a desire to feel valuable, powerful, or important, just like you?
