I don't get this complaint. Protesting is supposed to be confrontational and disruptive. Any protest worth a damn has been that way.
Why are so many of you acting like Bernie Sanders is some sort of sacred cow? This is presidential politics and that shyt gets rough; no one should expect to be treated with kid gloves who decides they want to be president. And this stuff is actually being effective because it is making Bernie's campaign address racial issues when they had no intention of doing so officially at all.
Bernie has an optics issue that his team needs to address (the fact that his entire senior campaign staff is nothing but white men is another example of his tone deafness on diversity) and is going to have to learn how to craft his message in relation to the racial issues that are a major point in this country.
		
		
	 
I'm ok with the protest, I'm ok with the shouting, I'm ok with the disruption of a meeting/show/[insert gathering]. What is "the wrong way" IMHO is when you ask a question let a mutha fuka answer the got damn question. Now instead of being able to dialogue with Bernie on national television or in front of a large audience the candidate is going to throw out some sound bites or lay a plan out on paper. I get the importance of the message though. Also, in terms of overall strategy, smacking your ally in the mouth is probably not the best way to go about it. I notice mostly women up there too, in fact I notice almost exclusively women doing all this...unless I missed something. IF i'm correct though, it's pretty fukin suspect and shady that the feminist movement (a la Hillary) is hijacking BLM. 

 i might be wrong on that point though. 
Never the less it's the same shyt I tell Christians. If you want to preach/convert/educate somebody you can't get all in their face yelling You're WRONG YOU"RE WRONG and expect them to agree with you. That type of action typically turns more minds away form your cause then towards it. 
Sure did Bernie release a statement? Yeah absolutely. How many "liberals" saw that, including myself, and were more upset than not. Short term gains (a statement) are hardly worth losing your populous appeal. 
Also, 
Let's face it the GOP is in their death throws AND are/have been the largest threat to minorities and the underclass, now at the eve of their demise liberals are going to fracture. 
Ultimately this is not really a good thing IMHO. Or rather it's not a smart thing and there are ways to achieve these goals without alienating allies.
