I don't hide my identity, but I've had reason to regret it.
On the subject of the V-22 osprey, the testing of which pretty much took over my life from 2001-now, I became sort of an icon of reporting the good, along with the bad. It's been a moral issue for me. In the process of debunking certain strident critics of the plane in several on-line forums, I became the object of derision of a couple of diehard critics who used the same principles of argument we see all the time on DU or daily KOS. One POS even wrote a 3-page letter to the Secretary of Defense demanding I be fired, investigated, jailed, or shot. Nothing came of it, and the whole mess made me more of a hero to the Marines flying Ospreys at New River, and got me a raise to boot. But it was a pain to go through.
Moral of the tale: there ARE nutjobs on the intarwebz; stay clear of them.
