In case anybody doesn't get the point, this is a gish gallop.

Gish Gallop is a technique, named after the creationist Duane Gish who employed it, whereby someone argues a cause by hurling as many different half-truths and no-truths into a very short space of time so that their opponent cannot hope to combat each point in real time. This leaves some points unanswered and allows the original speaker to try and claim his opponent lacks the counter-arguments.

The problem with most of these questions is that they are actually little arguments containing hidden premises.

A hidden premise is a premise that is required in order to reach the stated conclusion, but is not itself stated clearly in the argument.

"How did they "Train" the 54,000 Mules?" is actually something along the lines of:

• Dinesh D'Souza claims there were 54,000 vote mules.
• Being a vote mule is skilled labour.
• Skilled labour requires training.
• Training 54,000 vote mules would have been infeasible.
• Therefore, Dinesh D'Souza is wrong and there were no vote mules in the 2020 election.

You ask some good questions- some are clearly answered in the movie- but others will require additional research. Are you offering to help?
