False. No matter what is said, you merely allege that it isn't "backed up."
The burden of proof is on you to counter. Such as your allegations of the other's "failures" to prove. Again you have no support for that, do you? LOL!
Go miscite Reagan again. And that wouldn't be a change of subject, but appropos of your lack of credibility.
If you can do that, then I know I can teach you to give me evidence of just one "disavowal" that is now "debunked." School's out.
