Lefties are not interested in conversation, even though they always are looking to “start a conversation” on a myriad of issues. What “start a conversation” really means is, “Let me tell you why I’m correct and why you are a horrible, brain-damaged person if you don’t agree with me.”
Righties are not interested in compromise, even though they claim to want compromise. When they compromise, they are really saying, “Let me tell you why I’m correct and why you are a moron if you don’t agree with me.”
I have decidedly conservative attitudes. I think that what people do in their own house is their business. Who people leave their assets to when they die is their business. Not the business of anyone else, especially not the governments.
So, I think one reason for the divide is a fundamental lack of respect – lack of respect for the intellectual capacities of those who think differently (Lefties: Guilty), and a fundamental lack of respect for the morals and feelz of those who think differently and are easily offended (Righties: Guilty).
Another reason, is the fact that the Government are getting involved in things in which they have no place nor authority. There is a battle for control in the COL, so that certain views and morals can be imposed on the rest of us. This battle is being fought with hate and vitriol.
The final reason is the replacement of news with opinions. Most people get their “news” from purveyors of political opinions. News should be presented as Who, What, When, Where, and How. Why is the purview of opinionated lefties and is not news.
