Hi, AD!
I didn't really think you personally meant to offend anybody, it's just that this particular term does carry some very negative connotations, and can be highly offensive to some people.
Perhaps I'm more sensitive to it because my life is here in Japan, most of my friends are Japanese, and the woman I am going to marry is Japanese.
That term doesn't faze me at all when I hear it in movies (heck, even cartoons!) of the period, because that was acceptable language during the conditions that existed then, and I am no historical revisionist.
But it really does put a spike in my heart when I hear it used in the modern vernacular, whether it is used with malice or not.
I've never heard the term "roundhead," so I have no idea what connotations or meaning that may have for Danes.
I'm American, but certainly, "yankee" doesn't bother me at all! I don't even get upset when, upon hearing I'm from Georgia, someone calls me a "redneck!"
I guess it just depends on a person's individual level of sensitivity, or knowledge of the background of a particular word.
Anyway, I understand your position, AD! "Japanese" ain't that easy to spell, that's for sure!
And by the way, you are absolutely right: those guys ARE crazy!!
Absolutely insane modelers!
And they can drink beer like nobody's business!
Now, let's build some models!
