So your problem is that we should only care about the votes of Democrats in safe blue states? Is the idea we shouldn't count the votes of Democrats in red states in the primaries? This makes no sense.
Yeah the DNC being meaningfully anti Bernie is QAnon level conspiracy nonsense. At a basic level of analysis it makes no sense. I've read up on it plenty and it only confirms this. Ideological, partisan nonsense that is honestly embarrassing for the left wing.
I would vote Bernie and I think he should have been President. But he didn't get the fucking votes so he isn't. Tough luck.
