I encourage you all to read the actual facts instead of interpreting what you see from a video filmed inside a group of chaotic Sanders supporters, and then reciting that *interpretation* as fact. Facts are not things that you imagine in order to explain something. In this case, the facts are far larger than what the videos show and in fact, the videos omit that the things that were rejected were rejected on the grounds that they were against the rules.
Sanders supporters designated by the Sanders camp made the rules and approved them. That’s a fact. A handful of supporters tried to change the rules afterwards to skew the rules in favor of their candidate and they weren’t allowed to.
If you have a problem with that, you have a problem with democracy and maturity.
