From what I can recall, its only gotten this bad as of the last four or five years. Before then, people could reasonably disagree and go on about their day. I personally lean towards libertarian or anarcho-capitalist on many issues but I have had great friends that voted republican and democrat both. I think the change has been the result of class and racial division spewed forth by the collage/university systems and blatant propaganda spread by the liars in the media. It seems any little insignificant difference between groups of people is greatly magnified by these institutions and it has us at each others throats all days of the week. I have not seen many events thrown by people on the left outright shut down by people on the right but if anyone can point out some i could use some enlightenment on the issue.
Islam has killed millions in the last decade, lets focus all attention on Christianity!
