IMO, there is a difference between being brave and being stupid.
Granted. As the invaluable Mr. Silverback has already succinctly observed, however: "Penn & Teller are millionaires. They could hire bodyguards and security experts galore."
As a useful corollary to your own credo, above: there is, likewise, a yawning, cavernous difference between being prudent and craven. If even those blessed with both great wealth and easy, frequent mass media access are so glibly ready to lie down, lamb-like, and meekly submit... then: NO ONE shall willingly stand, ultimately, and we are already lost.
