But I think that the irresponsibility of the Tea Party 'targeting' certain congresspeople has about as much to do with Loughner as the irresponsibility of not paying your taxes has to do with the feeding habits of wolves in Southeast Asia.
If half of the crazy shit the tea party said were true rather then absurd, childish lies, then the logical course of action would be armed rebellion against the US government.
If we actually did live in a country that was being usurped by a Manchurian candidate. If they actually did want to start forcefully euthenizing grandma. If that kind of stuff was true, then it would make sense to start the second amendment solutions. But we don't live in a world like that. We don't remotely. We live in a country where the majority barely has the power to pass laws that the opposition dreamed up 15 or 20 years ago.
We have politicians who aren't just playing with fire, they are playing with fire in a dynamite factory. They don't just say "kill them" they tell people with a straight face that we are actually going to dictatorship. They repeat this overblown rhetoric for months and months and months, saying death panels and birth certificate and socialist plots. If they're words are taken at face value, they are making a persuasive argument that it is the time for revolution. They don't just say "have a revolution" they say exactly what they want to fight against.
Most people can see that their bogeyman is imaginary, that they are just engaging in overly enthusiastic political rhetoric. But most people don't go and try to kill their congresswoman. This crazy man honestly believed that we were living in a dictatorship. An evil dictatorship that needed a revolution. It's not exactly a huge leap to say that we need to take a long, hard look at the party that has spent the past two years relentlessly repeating the idea that we are turning into an evil dictatorship.
