As I've said, no one is initiating force against an unwilling party.
Why has Dignitas been under criminal investigation by the Swiss authorities?
I haven't the faintest idea. The first time I'd heard of them was in the context of this article.

You really ought to do your homework, because if this is the way you conduct yourself the other pseudo-intellectual secularists are going to eat you alive.
