How can we open up to those around us?

Over the past few days, I have been talking about the fact that we are just one person and one individual within a society that is diverse. Cardinal Burke made some remarks today about the exclusivity that are seen in many churches, including his own. He was stating the inferiority of certain populations of Catholics that the Pope is trying to reach out to and trying to reconcile with on behalf of the Church that he happens to be a part of. It is people like him that are bringing down the hard work of the Pope. The topic of allowing gay people and divorced and remarried Catholics to be a part of the mainstream is something that is also prevented from being because of old doctrine. There are some people in this world that refuse to recognize the existence of people that are different then them. Instead of focusing on what makes us human and what makes us united, we tend to put a ton of focus on what is making us different, building up societies around those differences, and it means that there are a lot of people that spend a lot of time fighting for equal rights. It is only in the past couple of hundred years that we are able to see some true forms of equality come about. We need to understand that there are a lot of things that differ us in a variety of ways, but we need to focus on the things that make us who we are as humans and the things that unite us as well.
