Nothing against Rush of course.
Don’t bring persuasion to a gunfight.
Having worked with rabid liberals at a union for 10 years, sometimes I would just act dumb and ask them to explain how something worked according to their beliefs. I’d just keep asking, and most of the time they would end up walking away with their head down, or sometimes get irritated because the knew they didn’t have a good argument.
Nobody is going to persuade an idiologue of anything.
