I was joking with my comparison, but I do think people tend to over-react when it comes to MR's (possibly because they are new). I have done plenty of flights with R/C helicopters and have never had one just fall out the sky for no reason, it's almost always some kind of human error (oops battery ran out of juice, or oops that was a bad solder joint, oops i lost orientation, ect). A responsible pilot doing proper pre-flight checks, and knows the limitations of his gear well (battery life, flight range, piloting ability), would be very safe IMHO. I think MR's are very capable machines and can be very safe if done right. Trust me, my or anyone's worst fear is hitting someone with a MR.
That's probably a good call, Kilby
