Dang, I was going to write the exact same thing myself--I don't have any problem with someone blasting bitcoin, even if it's with lies, because I believe everyone should be free to express their thoughts no matter how twisted they are. Lies and misinformation can be countered with truth, and if that doesn't work there's always the ignore button.
I really agree on this, the ignore button is way better than us having to talk to people like that who don't really care about the truth. I've advised that user to stop all his bullshit, but I don't think I've succeeded either so I've considered the ignore button. LOL
