It is weird.
Political correctness is all about creating a climate of fear, fear of the thing itself or of being perceived as that thing etc.
For some reason, politicians and various do-gooders like yapping on about an "obesity epidemic" or "obesuty crisis" (being a complete misuse of those words), so I had hitherto assumed that being fat was politically incorrect and persecuting fatties was politically correct.
Apparently not. From The Daily Mail:
A weight-loss expert has blasted retailers for using size 16 mannequins, claiming they are 'normalising' obesity.
Presenter of the TV show Fat Families, Steve Miller told MailOnline 'political correctness is encouraging people to stay fat'.
He has urged society to adopt 'shock tactics' to tackle the obesity epidemic head on.
In any event, those size-16 mannequins look a perfectly normal shape to me, the size-10 ones are definitely borderline anorexic.
Presumably Steve Miller is a joker who wants to take the money and run.
