Throwing away the votes of millions? Sounds like a big lie.
I don't think anyone disagrees that voting should be easy and safe. But there are policies being pushed like ballot harvesting, not having firm cutoff dates for mailed-in votes and banning reasonable forms of voter identification that are highly debatable. Also the Democratic party seems to have a fixation with federalizing election machinery, which seems to have the benefit of standardization but actually is of dubious constitutionality and concentrates points of failures in a manner that I believe actually makes elections vulnerable to bad actors.
You assume that there is a coherent reason that a few thousands bums bumrushed the capitol, and there was a coherant and organized plan. The President incited a riot to disrupt a Congressional proceeding that shouldn't have been happening in the first place. He should have been convicted of this at his impeachment. But I don't think it helps the case to overstate what it was.
