I have read your piece and I find your attitude at best insulting and at worst arrogant. Not because I am a progressive or because I am white or because I am female, or any other reason than I think you are making a great many assumptions about things that are very complex and need to step back and stop attacking the only candidate who in his entire career has treated you with respect, even to letting you take over his rally, and worked against those forces that you want stopped.
I do not see you disrupting the GOP/Tea Party candidates rallies. I do not see you disrupting the Clinton rallies. All that gets any press is the disruption of Bernie Sanders rallies. Where are you pushing your way into and taking the mike away from any of these other candidates? Oh, that's right - the Clintons are suppose to be your big supporters, right? Well, then tell me how come it was Billy who cut apart the safety net that was helping African-Americans to rise out of poverty for nearly 40 years? Tell me how allowing cuts to child care and early education programs and public school funding helped African-Americans, since it was started under Clinton, put on steroids by the GOP and been constantly chipped away at by the GOP/Tea Party members of Congress? And while you are at it, tell me how one man, an African-American president, has been able to change one thing in the African-American community when faced with dissension and obstruction from his own party's faux progressives and corporate shills and the GOP? And yet, you think that only Bernie Sanders is ignoring you!?! Get a clue: they are all ignoring you!
And antics like hijacking the campaign appearances of Mr. Sanders is not going to give you any supporters. In fact, you are undercutting his support, which is across all party lines, and which could actually carry into office people who would be willing to address the injustices you and your families are suffering from. So instead of lambasting him, why don't you actually try to get him elected by letting him reach out to people of all races, economic levels, and tell them how they have the power to change what happens in places like LA, Ferguson, Chicago, New York, and across this nation. No, you would just rather shut him up! Not exactly a brilliant tactic, unless of course you are being paid to shut him up and need the money to finance your cause.
You want progressive voters to address your issues? Well unless you help the American people elect a progressive Congress and a progressive president, like Mr. Sanders would be, by actively working within voter registration movements, GOTV movements, and educating people reasonably at rallies of thousands (something Mr. Sanders is giving you the opportunity to do, by the way - I do not see any other candidates so willing), you do not stand a chance of getting what you want because the corporate DNC led by the Clintons and the GOP/Tea Party are not going to let you have it.
You want people to hear about what is happening, what needs to change, then do not do what alienates people from your cause by silencing the one man who has been consistent in his stands against all these atrocities and the underlying causes - poverty, bigotry, inequality, social injustice. He knows the stats you have quoted and he knows that problems roots and what needs to be done. He has known and been fighting against them for over 50 years. He probably knows them better than you do. You have easy access to his events, but understand there is a reason that is so - he wants to have everyone hear his message about how to stop the atrocities you talk about, not just people who can afford high priced tickets or the wealthy donor clubs. Do not silence him - You need him.
And you need the voters he is reaching if you want to change anything. It is not progressives that are interested in your votes over your humanity, it is the others you ignore and do not disrupt. It is the likes of Hilary Clinton who targeted a black minister with hate rhetoric in 2008 by using a white ambassador's remarks to say President Obama was hearing radical ideas in church, and it is the current clown car candidates of the GOP who work so hard at calling your victims every name in the lexicon to deflect your anger from injustices to numerous to count. These are the people who are more interested in your votes than in your humanity, and until you recognize that simple fact, you have got the argument all wrong about the progressives and about Mr. Sanders. But, of course, they use high priced thugs to keep protesters away from their rallies and their microphones, so they of course understand your issues? Wrong!
You have legitimate gripes, but unless you want voters to take you seriously instead of being repelled by your actions, I suggest you stop hijacking Mr. Sanders campaign appearances and start actually working out ways to make yourself useful to him and other progressive candidates in order to drive out corporate candidates within the DNC and elitist wealthy GOP/Tea Party candidates.
