There were international observers in the 2020 election and they found no evidence of fraud [2], and many mainstream media sources that I hold reliable, (e.g. [3]) fact-check multiple claims of election fraud and nothing has showed up that would suggest that the election was "stolen".
I don't think it is at all preposterous to assume that the 2020 US election was fair, unless you subscribe to a view that the global mainstream media apparatus is in on some grand conspiracy.

We've gone from "haven't seen evidence" to "seen evidence at probability P-prime". Trust in an electoral system is an important enough issue that this should be investigated to the same thorough degree as a capital crime.
Did you mean to send a different video? Or are you deliberately misrepresenting evidence to support your position?
