Is anyone really surprised?
Well I am not surprised, when a celebrity, ( They don't have to be experts, or even own half a brain. ) makes a gesture, some sheep always follow, and a few always fall over the cliff.
If you are a celebrity and you do have half a brain, you have to understand that the modern media makes your every small act, a powerful example, and therefore you should be very guarded. It is a pity you can't charge them with manslaughter.
