Just to be clear, I'm not concerned about whether it offends me or not.  I think it should be deleted because:

1.  It's bad for Bitcoin.

2.  You're threatening an actual person, with family, maybe kids, etc.  He may be an asshole, but he doesn't deserve to have his life threatened. 

It's funny, you cry fascism, but in many ways your absolutist world view and view on violent speech closely mirrors the *real-life* fascism I came face to face with in ex-Yugoslavia in the 1990s.
