Every candidate has asshole supporters*. It's easy to build a narrative around the particular demographics of Sanders supporters, so people talk about 'Bernie bros', but I suspect we'd find roughly the same attitudes if we looked at the support base of any major candidate (Except Trump. Trump supporters are a breed of their own)
*Except, of course, for Lawrence Lessig, who doesn't have supporters at all.
No, I think that there is a difference. There has long been this cult like support for Bernie because, in many ways, a lot of his supporters believe that not only is he perfect, but he is objectively better in every facet than Hillary. This notion is absurd as (1) no one is perfect nor is anyone a liberal messiah, (2) Bernie cannot be better in EVERY category than Hillary, (3) a lot of this is subjective and not objective.
I've been aware of the BernieBro for months now. In fact, I had an awkward situation in which one yelled (literally) at me for saying "eh, I support Hillary." Clinton certainly has idiot supporters, every politician does. However, I have not seen anywhere near the same level of hostility from Clinton supporters that I have seen from Bernie supporters over which candidate one endorses. Personally, I think a lot of it has to do with the "enthusiasm gap" combined with Bernie drawing younger, and at least in my insignificant opinion, more naive crowds (a naivety which grows into a belief that Bernie will change the political system for the better).
While a lot of this speaks only to my personal experiences, that really is all we have going either way (that is, this is blown out of proportion I have not seen Berniebros vs. I have seen them and they're real and obnoxious). There isn't going to be a scientifically conducted poll on this phenomenon.
So, in closing, Sigma, you're an asshole. So now that we've established that, 100% of Lawrence Lessig supporters are assholes [/sarcasm]
Edit to clarify: and when I say "for the better" I mean similar to Obama. Obama made grandiose promises of change during the election, and ran to the center immediately after election. Nevertheless, I think he has been a great president. So, at least in my opinion, grandiose promises of change don't materialize, but a centrist democrat is better than a republican. And this is what I am talking to about the naivety, largely my own experiences 8 years ago with Obama.
