Semi, I think Bill was just trying to prevent this thread from turning ugly the way the other one on this topic did. He didn't say he wouldn't want anyone's good wishes for the child. What he meant by detractors is the ones who ridicule the very prayers he was asking for. Remember JimiHendrix' old standby line - "Prayer is the least effective thing you can do"? THAT'S the type of thing he was trying to avoid.
I'm sure the child's parents have access to a computer, and because Bill has told them about asking us for prayers, they probably see what is written here. The last thing they need right now is to read comments like the one Jimi made.
