She didn't do anything to you. She extended an olive branch to Sanders and gave him concessions. Allowing protest at the DNC, branches were extended again and again and all Hillary got was the perpetuation of the 'rigged' narrative and "both of them are equally bad".
If that crowd was actually so ardent about progressive ideals, they should have voted for a future from which those progressive ideals could be planted and nurtured. You speak of an echo chamber, but are the Sanders supporters not ensconcing themselves in one to talk about how shitty Hillary's campaign tshirts were? Because that was what was important?
And what good is the VP spot? The idea that it should have been conceded to Sanders is incredibly stupid, largely because he would be more effective in the Senate, where you would want him possibly chairing committees!
In the end they didn't actually care about progressive ideals, they cared about their moral purity. They never WANTED to vote for Democrats, all of them went re-registering as independents after they finished sitting as DNC delegates. You want to villify Hillary because it is easy to blame her, but this woman ran a campaign about inclusion. Her campaign cooperated behind the scenes with Sanders campaign demands, on the platform, on getting DWS removed, on more debates. These overtures were not returned until a month after she sealed the deal. And even then the busters were Never Hillary. They were the ones who made the election about her, for them, rather than about policy.
Her campaign was not about her. The campaign shat out a book on policy. The videos on her youtube channel released over the duration of the campaign were video stories of the people who benefited from policies and legislation that Hillary helped pass. The focus has been on those people. Just not the people that you wanted focus on or the policies that you wanted focus on.
The media circus ended up fixating on the candidates in the campaign regardless of what policies Hillary wanted to talk about instead. That is outside her campaign's control.
The Sanders supporters screamed a lot too, and they were worse than ardent Hillary supporters because they allowed sexism and racism to fester within their ranks. So there is no high ground there.
