Alone in a crowd

So let’s say someone is very social, a gregarious outgoing person willing to meet and befriend new people all the time, does that also make him/her an open, fair and reasonable person? For the majority that seems to be the view.
I contend otherwise, I myself am not very good at social interaction, and do understand that it’s my own inadequacies that do no let me mix well with people. More often than not it's my inherent introversion, coupled with my laziness, that prohibits me to put in the effort required to maintain relationships. However, sometimes there is a third factor - when I meet someone who by a phrase, thought or action show that they have rigid mindsets that will not allow for any new information, people whose viewpoints are so preset that not even one speck of doubt can enter their minds.

These people are so fixated on their rigid snapshot of the world that wonder, creative impulse, empathy, and a feeling of fairness are impossible for them. I then unconsciously make the decision to keep the relationship at arm's length. I never try to change them; usually it’s a waste of time and effort and can destroy the relationship entirely. I try to remain civil and at peace with that person.

The saddest thing is that a majority of such have sharp minds, although trapped within a false picture of the world which never gets out. When presented with any information that contradicts their views, they just shrug it off. They don't want to know. Some don't want to be confused by the facts because it means they may have to change; maybe their lifestyle, their church, their politics, their morality. They are very exasperating to debate with; not only are they conceited in their certainty that they are right and everyone else is wrong, they are also unable to understand how anyone could really see things in a different way.

I feel they are the ones with true issues of social interactions, in spite of their numerous engagements and large social circle, they are the ones truly reclusive and alienated, walled in by their monolithic thought.
