All right, from the top...
Shrek is an unappealing character
Isn't the whole point that he is appealing and charismatic in spite of his unfortunate background?
teaches unfaithfulness,
Who, exactly, are they thinking of here? Even Donkey remains loyal to the unlikely suitor who tries to win his affections, despite a mixture of incompatibility and terror.
has low, coarse crude humour,
OK, I'll give them this one.
promotes homosexuality, cross dressing
Where does homosexuality come up? As for cross-dressing, there is a woman bartender who looks like a man, and that's all I can think of.
and divination (super-natural means).
Because it's set in a world where magic exists. It's also a world where animals talk, dragons roam wild, and magic potions can change your appearance. Shrek isn't suggesting you should go careening through a potion factory in the real world, or recruit the nearest cat as a sidekick, so why should it be promoting divination in the real world either?
By allowing these influences, McDonald's is numbing the hearts and minds of children.
If the kids never go to see the film, they won't know that Shrek is immoral, coarse, or unappealing from one little plastic toy. So why doesn't Judith just avoid taking her kids to see Shrek? They could stay home and rent something more suitable.
