I'll indulge you.
Let's go 1 by 1
1) statistically improbable turnout numbers in key Democrat counties
-- Give an example. Turnout was high everywhere. What is "improbable" here other than "I don't like that so many people came out to vote against Trump"?
2) uniform Democrat "comebacks" in swing states based on submitting counts from Democrat strongholds long after Republican counties were finished counting,
- Entirely expected and discussed months in advance due to the split in the use of mail in and early voting. In fact, deliberately engineered in many cases by Republicans to create a narrative of suspicion.
4) large batches of votes which, improbably, were all cast for Biden,
- Democrats cast votes for Biden? That's suspicious!!!
5) vote updates overnight solely in favour of Biden when counting had, apparently, be stopped,
- Votes counts are batched and reported later. This has happened in every election.
6) objectively proven unlawful resistance to party oversight of the tabulation process in Democrat strongholds,
- This should be good. "You are allowed to be 6 feet instead of 10" is not proof of resistance to party oversight. Please show this objective proof. (I have seen judges point out that the GOP complaints they didn't have people observing were false and then dismiss the case, though.)
7) use of machinery for signature comparisons (in states that even required it) that had inexplicably low rejection rates,
- "I don't like that they aren't rejecting Democratic voters" is not "inexplicably low rejection rates"
8) a media which is aware of all of these concerns, but calls election challenges "unsubstantiated" and calls someone who has neither been certified by any state, nor by the electoral college, "President Elect" despite the absence of any concession by his opponent. Only a fool wouldn't insist on proof that all of these things have an innocent explanation.
- A media that follows the norm of calling someone "President Elect" when they appear to have won the election is not suspicious. These kinds of crackpot theories come up every election, they just usually don't have the losing incumbent trying to fundraise and organize resistance off of them, aided quietly by GOP power brokers who figure if he fails they can blame him and say they didn't really do anything and if they succeed they get to overturn the will of the people they don't think deserve to vote anyway.
