This is really good! I would like to add a few things, though:

First, self examination is a necessary aspect of this, but it could also cause your view to change. We humans have an inherent need to be right, which you talk about in the post in a way. But, examining what you believe and why could actually lead to you realizing where you are wrong on a topic.

Second, realize that a person is not the sum of a single one of their opinions. A person may have a position that you despise, but there are likely many other things that you agree on, or are simple not relevant to you at all. Aside from this, respecting the person as a person, instead of seeing them as personified by that one opinion you don't like, can go a long way to helping dialogue.

Third, look for common ground. Often, you can use that common ground to at least not be at odds with someone, but at most, you could make a friend that you can have really good conversations with.

Fourth, you dont have to be right. Its ok to be wrong occassionally, or in the very least, acknowledge where you simply have an opinion, and it is not required that the other person agree with you.

Fifth, apologize when you offend or wrong someone unnecessarily. I don't think I need to elaborate

Lastly, learn when to separate from someone. You cant run a house with someone who has a completely different way of handling money than you. It will lead to fights and problems between the two of you.

Just some short additions to an already great post. :)
