You're confusing comparison with equivalence (or at least taxonomy with moral judgment). Though I'll grant it would've been possible for me to be clearer that I'm not saying the rhetoric or 'revolution' or even 'resistance' is equal to Palin's sins. But my post was mainly focused on introspection, which generally involves considering one's own actions independent of the worse actions of others, and it's precisely this sort of reaction which I find problematic. It's symptomatic of an unwillingness to engage in any sort of reflection, which you find yourself freed of because the other side is worse (and I would point out I'm no saint in this regard and think the concept has its limits, such as during elections, where last year I argued it was unproductive to focus on the deficiencies in Clinton in what was an entirely relative contest). Acknowledging that there is a causal connection between political rhetoric and violent actions is a step in the direction of considering whether the left could be doing something better, which doesn't involve any consideration of whether the right could be doing something better. The Giffords example simply supplies evidence of the logical connection.
I honestly don't understand what the 150+ people example is meant to be replying to, but I assume it's a reflexive deflection from any sort of critical reflection.
Shifting to the problem I identified in my post itself, I guess part of the issue I have is that the left seems to have adopted the word 'resistance', but then kinda approbates and reprobates as to how that ought to be put into action. I'm not opposed to the use of the word 'resistance' in the current circumstances, but only assuming it's given some meaningful content. If the left constantly uses the word 'resistance', which is quite a strong word, without providing any meaningful content for that term (and given the word signifies something more than normal participation in the democratic process, that alone wouldn't be meaningful content), then people left to their own devices will provide their own content, which will in some circumstances end up being far more severe than is intended.
I sincerely doubt you believe that.
