Is it normal conservatives have been more violent lately?

Two days ago at home, my dad called me a "nigger lover" and started shooting at me. I managed to get out of the house. I called 911 twice on my phone and both times they told me off. I had to make it on foot to the sheriff's office to get someone to help me. I told my friend about it and he said one of those conservative pundits his dad likes said to a caller that any true patriot would kill any member of their family who was a liberal. I also found out a woman who goes to my university was shot by her dad after she said she didn't like Romney. A guy I follow on Twitter said that it was reported in his local news that a man killed his son "for being a liberal." Is all this just a coincidence or has someone riled up the Republican mob?
