I've not noticed any jokes about Japan. That's kinda sick tbh. The only statuses I've seen are 'praying for Japan' or 'my relatives are safe in Japan'.
How do you spot a japanese prostitute?
She's the one in the fishnets.
I have heard some the japanese jokes, it happens we do it, some of them are funny in thier own way. I have no real issue with it, yes its insesetive but so's Fankie Boyle and people adore his humour.
What i dont like are the nutters going "they deserve this, this is gods judgement, this is revenge for Pearl Harbour" those people are revolting and truer inditement to the viciousness of man than a joke
People are allowed to say what they want. Such is life.
