Sarah, perhaps Andreas' family and supporters don't have the time, space, or emotional energy to deal with the inevitable attacks that will come, no matter what they do or say.
The internet can be a very cruel place. Just today, I read a post that said Andreas' family is acting like "the Mafia."
I think that they're not ready to deal with these attacks that will be directed toward Andreas and his teachings, no matter what his cause of death. He was attacked and belittled during his life on earth, so this is to be expected.
I think that his family is grieving and I respect this. They will deal with Andreas' death/rebirth in their own way and in their own time. I'm thinking that we've gotten used to "reality" TV and Facebook but some people want privacy in their lives.
I'm seeing some people quick to judge them but it's impossible to know the truth unless we've walked in someone else's shoes.
Perhaps Andreas talked with his family about it before he died and asked for his death to be handled this way.
