While I agree it is dangerous, I differ on the reasons why. If Dr. Paul is challenged on this through the mainstream media rhetoric or in debates, I have full confidence he can answer why he made this statement and support it fully. His answer will make alot of American's take notice and want to research more. I think if they try to crucify him on this, the "blowback" from it will be to our advantage.
The reason why I think it is dangerous is because people get killed for this sort of "truthfulness". I'd be surprised if he is asked to even explain himself in a debate as this isn't the sort of thing they DON'T want debated, if you know what I mean.
Have you researched the Federal Reserve or the illegality of income taxes? If not, I can provide some great video's for you.
