Well I will say I can identify with your sentiments, and it's sad the complete lack of patience and respect for differing opinions.
I wouldn't criticize that as being political, it's the effects of human behavior.
Landmark Forum discusses this behavior for example:
In the Already Always Listening segment, we visit the notion that while we think of ourselves as open-minded and objective, in fact our approach to ourselves, our circumstances, and others is often filtered and even obscured by pre-existing notions and ideas – by our upbringing, our values, our past experiences.
In this session, we see those filters for what they are – an all-pervasive influence that profoundly colors our relationships with people, circumstances, and even ourselves. An awareness of these filters, and a recognition of the striking limits that they impose, allows for a refreshing freedom. People, situations, and our approach to life alter dramatically.
You're covering psychology territory, that would be my assessment.
