You claim you can "just encrypt" your email, but it was the creator of lavabit, the "secure" email system that Snowden used, who stated essentially that email can NOT be made secure. It's not just a technology problem. When Secret Courts tell citizens they can't talk about Secret Orders, "encryption" isn't the solution. It's not just what you're saying, but with whom your talking to (e.g. metadata).
You may not agree with that, but you can't declare that no one else can believe it. You can read PJ's statement for yourself. You may not believe her, but you can't look into her heart and know that the reason she gave wasn't sincere:
My personal decision is to get off of the Internet to the degree it's possible. I'm just an ordinary person. But I really know, after all my research and some serious thinking things through, that I can't stay online personally without losing my humanness, now that I know that ensuring privacy online is impossible. I find myself unable to write. I've always been a private person. That's why I never wanted to be a celebrity and why I fought hard to maintain both my privacy and yours.
