Well, if you want a pervert paedophile to get excited at the suggestion your kid is making by wearing such a 'fashion item' so that he (or she) grabs your kid to be abused by a network of disgusting men and women, provoking you into calling for microhipping all kids, then I suppose they are simply harmless fun.
Personally, I do not think they are harmless fun.
I think they are the next phase in the war on children.
And the aim of that war is to sexualize children, to incite paedophiles into comitting more crimes against children to provoke calls for microchipping.
A few years ago Playboy, the adult porn company, was selling duvet covers, towels, stationery, all sorts of stuff to kids. There was outrage, outrage that is not apparent with the shagbands.
But make no mistake; these shagbands are just another battle in the sexualization of children.
