Yeah, I agree, but it doesn't get a rise out of me anymore. It's expected, and part of the background noise of the political scene to me. Repeating what comes out of the anger-unhinged Left is normally just pissing into the wind. The MSM will filter, ignore, or downplay it.
The only time it "helps" the Libertarian/Right side of things at all is when what they say is so egregious and juicy, it gets play in the MSM despite their normal bias, and then it maybe sways a few undecided/squishy-middle types as to what the Left's all about, and it maybe gets a conservative over the top in some election cycle.
Mostly I just file it away for a rainy day to remind me of who we're dealing with is really like inside, and make things a little easier should it ever actually progress past just shouting and words.
