Some republicans do so in order to have the weaponry available to kill, among other things, offending democrats:

N.C. man accused of threatening Barack Obama

CHARLOTTE, N.C. - Authorities say a North Carolina man will undergo a psychiatric evaluation after being jailed on a charge of threatening to kill Barack Obama.

Federal documents identified the man held Friday as 48-year-old Jerry M. Blanchard. A criminal complaint says witnesses overheard Blanchard twice last month threatening to kill the presumptive Democratic nominee. [...]

Separately Thursday, a 22-year-old man in Florida made a court appearance in Miami on charges he threatened to assassinate Obama. That man also has denied making threats against Obama.

Surely you’re familiar with the recent church shootings in Knoxville, TN? A republican nutcase thought it was time a bunch of democrats should die. So he entered a church known for it’s tolerance for gays and opened fire.

And this is the party most Christians gravitate towards.
