You know, I, an American, have wondered for a while why it seems that only Americans tend to be SJWs, or at least the most offended at things. I think I know why now, or a least a theory.
I think its all backlash against the "Culturally Ignorant/Insensitive American" stereotype.
Make no mistake, most of us are very aware of how the rest of the world tends to view us in the most common of stereotypes. Like the loud-mouthed, gun-toting, overweight, overly patriotic stereotype, which is primarily a caricature of the right wing conservative half of the country. I think the more liberal of the country has taken the stereotypes to heart, and are dead-set in being as 'Un-American' as can be, including "Don't say anything offensive to anyone from a different culture."
One of the other posters on this topic said that he jokingly refers to himself as a 'sand ******', to which some of his Black acquaintances laugh along with, but the White girl is the only one who popped up to say "That's offensive!"
She's right, to a certain extent. How long has it been since the idea of N-word privileges have come into play? She thinks it's offensive because she's been taught that it's not okay for her to say it because it's a slur against ethnic minorities, and because she's of the White majority, she's knows that nobody would forgive her if she ever said it, even as a joke, except if she said it as a joke among ethnic friends who know she's joking. We've seen several times in the media when somebody even slightly lets slip anything that sounds remotely insensitive, even if it was a joke, they make as big a deal out of it as possible, many time it's people of that ethnic minority getting on screen saying that they're offended.
I think things like this have made a large enough portion of the United States believe in the most common American stereotype, and they want to reverse it by being as accommodating and 'unoffensive' as possible. So they let people of other countries have a free pass with their behaviors because they consider it 'cultural tolerance'. It's okay for Brits to say '****'. They're not American, so we can't criticize them. The only thing they seem to unite behind is if someone does something they consider sexist. Then, it doesn't matter where you're from.
Even now, I'm sure many of the non-American Escapist community knows at least one person who completely believes the Culturally Ignorant/Insensitive American is more of a fact than a generalization. The kind of person who sees any cultural faux pas by an American as 'yet more proof of their ignorance', when cultural ignorance is by no means exclusive to us.
