Tea party activists showing up armed to political rallies, though, threatening others because it's their 'constitutional right'. Yeah, they are extreme.
I think this is a serious and common misunderstanding of the intentions of those who chose to be armed in public. In my experience with far-right types the gun isn't meant as a threat to anyone. It's more of a statement that they will not submit and be victims if their lives are threatened. The only reason to see that as a threat is if you plan on pulling a gun on them. Others are simply following their belief that the only way to keep our rights is to exercise them.
While money can't buy happiness, it certainly lets you choose your own form of misery.
