Despite the vicious and vile aspects of some ronchonner-ing here, the owner's head is so obviously odd that no-one, except those with their own 'problems', could be genuinely upset by what is calculated to be appear crazy or no more than a wind-up. There is hard (and soft!) evidence that US citizens are, typically and often grossly, overweight and, as most men would have to marry a woman, the description 'fat' is not unreasonable. It would be equally true of American blokes. Beauty, or Ugly, is just a matter of opinion.
On balance, I agree with the PAA decision not to pull his posting but don't know why they felt it necessary to single out Welsh (fashionable bigotry?) and Hebrew (traditional code for anti-semitism).
Scouse is not a language or race but, rather a dish, dialect or accent which, like its users, needs no defence.
