The problem is that it is a "joke" - you know, except in the sense that it isn't funny?
To quote from a blog I like:
Danny Dyer is not Al Murray the pub landlord, and he was not casually repeating stereotypes about the occupants of another country. Danny Dyer is not well established in the public consciousness as a comic character. Well, maybe he sort of is, but not deliberately. He’s not a fictitious construct. He’s a real person with real opinions, and when there’s absolutely nothing in any of the surrounding context of this remark to suggest humour or ribaldry, you can’t shrug it off with claims of “just a joke”.
