I'm not offended by the comment, just kind of amused someone went this far out of their way to miss the point.
But probably you are american and you don't even get irony nor sarcasm, you see, a joke ;)
And my point still stands, in 21st century people is getting so easily offended like if we are all now mentally weaker.
So on the one hand, sure, cultures are different between workplaces and industries, on the other hand, I really don't need anyone making smarmy assessment about my nationality or making insinuations about people of my nationality and our ability to comprehend irony and sarcasm to empathetically intuit the point made in the article.
The comment where the only point seems to be to attach a derogatory label to a group of people?
No, I don't believe it. I think attaching a demeaning label to a group of people is a way of saying you consider yourself outside of, and better than, them. If not that, what else was the content of your comment?
