No, I didn't. The poster claimed 20 million listeners. I don't believe that number, but it is quite beside the point. It will be sliced (cut) by a huge amount if he turns out to be a druggie.
So what if Rush was an addict?
It makes him a hypocrite and destroys his credibility.
IOW, whose business is it of anyone elses what kind and what amount of medication Rush took or takes?
Medication? LOL. Nice try.
But your other point is right on. EXCEPT for one thing, Rush disagrees. He says it's everyone elses business. He advocates jail for illegal drug users.
The 'legality' of a substance does not negate it being a medication. If you give a friend or spouse one of your prescribed pills does it then is it no longer a medication because they are taking it without government approval?
And that goes back to my point that the government shouldn't be in the position to determine what medications a person takes.
Why would YOU no longer believe Rush if you found out he became addicted to painkillers? He's not the first, nor will he be the last person to do so. It's a medical condition, not a character flaw.
