Yes, and people do and wear KKK things in real and online, because that also has become a generic reference to something bad.
You once again point to the easy example of asking specifically a Jewish family what they think of Lars comment.
Too easy. You ignore what the word and the concept has really become.
Using that logic, you cant say anything at all to anyone, as you will always risk hurting them or their values: about euthanasia for instance. You wont be able to make jokes about a car crash, as some will have lost love ones in one. Or anything about pedos because some will be in jail all their lives for having loved a 15yo consenting youngster. You may not refer flippantly to Cancer or the khmer rouge, just because some have suffered form it (imagine if Lars said ‘I I’m a kmer rouge, it would have bothered hardly anyone! even though millions also died at their hands).
Many jews are white and many are american; a good reason why we should treat their past suffering a lot more serious than the millions of dead in cambodia, or in african dictatorships.
‘I’m Stalin’ would also have had poeple chuckling in the aisles.
It’s all political and social correctness, what is fashionable and when.
I somehow believe Lars (who is far from stupid) was playing their game, and ridiculously, getting 100% reactions from them!
It is also what I believe might be doing Josh in this post, provoking some sort of simply grotesque responses from high-on-their-generic-moral-horses anglo-saxon hypocrites. After all, it is two boys playing on a public beach!
Which was the point of my comment above.
