Rand Paul is a medical doctor and the person you're replying to is a musician.
Yet the musician has watched the mainstream news media and therefore determines that their opinion is unquestionable.
Actual scientific debate (which is a fundamental process of the scientific method)..... is not even remotely an option to these people..
You're talking to a fascist. They will happily put you up against a wall for disagreeing with them and happily eliminate any possibility of discussion.
And its a hopeless battle against a hoard of people like this who all parrot the mainstream news media talking points and act like it's unquestionablely correct even though their knowledge of biology and science in general is questionable. But because the mainstream media says it it must be true.
It's fascism straight and simple. America is going down a pretty scary rabbit hole right now.
