Opinion: Democrats looked ready to unify. And then Hillary Clinton had to go and raise her hand

47. So let me help you with oen of those

That video wasn't doctored.
Biden has years of history saying he would cut Social Security and quite a bit of it has found itsef on video

But the video in question — of Biden’s 2018 remarks to the Brookings Institution think tank — was not doctored by Sanders, whose campaign this month stepped up criticisms of Biden’s record on Social Security.

Sanders’ campaign did say in a recent campaign email that “Biden lauded Paul Ryan for proposing cuts to Social Security and Medicare” — which PolitiFact said Sanders’ campaign got wrong. But there is no evidence that the campaign altered any video.

This put into question his sincerity about f he means what he is saying now about Social Security, especially when Biden won't explain why he changed his mind right when he decided to run for President.

So that point is false.

For the other two, 3 counterpoints

1. Hillary still has influence (or at least thinks she does) on the democratic party. She has spoken to every candidate except Sanders. So it' willful obtuseness to act as if she is a nonentity here.

2 Why is Sanders responsible for Bernie of Bust people but somehow someone like Clinton is excluded? Makes the whole "Unity " thing from centrists appear as a sham just to shut up anyone who challenges their power.

Your third point is just false on both part. But that's is a longer conversation you clearly don't have any interest in having to see as to how you just assert it despite the facts. So I guess I won't' delve into it either.
