The key to getting along with people of different political views is to play video games with them. It allows you to see them as something other than a dissenting block of text.
Also, it helps to not say things that are deliberately inflammatory, such as "The NRA is comprised of bad people" or "If this was a liberal, we'd read it in all the papers." Make more use of the preview function. Think about what you've said. If you want attention, take off your clothes and walk outside. If you want a fight, call your significant other by the wrong name during sex. Don't bring the ruckus here.
