Well, I made a copy of the thread because I figured it would get pulled down. For those who didn't see it, basically the OP started it by stating how ignorant Japanese people are because they don't know much about European history (errors in knowledge about Napoleon, Alexander the Great and the vikings were given as examples).
I can't say about what other people's deleted posts said, but my response was, in a perfectly reasonable manner, to point out that history in Japan is taught from an East asian perspective and therefore it was unfair to conclude that Japanese were ignorant just because they didn't know the basics of European history.
I then pointed out that European students don't learn much about topics like (for example) Confuscius, the Tang Dynasty and Hideyoshi Toyotomi. Knowledge about them would be considered a part of fundamental history to Japanese students, yet it would be highly unlikely that many European students would know anything about them. But from that fact you could not infer that Europeans were ignorant, as the OP attempted to do in regards the Japanese.
That post, which I put some thought into and even went to the trouble of looking up some facts in a Japanese history textbook to support, was summarily deleted by the OP for no apparent reason other than it didn't make Japanese people look stupid, which is apparently the only type of post that he considers appropriate.
The fact that my post wasn't treated with any respect made me upset. I don't mind being disagreed with or having people argue with me, but to have it just wiped off the face of the earth like that made my blood boil. And then when I (not unreasonably) demand an apology, they guy adds insult to injury by sending me an automated PM notifying me that I have been given an infraction.
I don't know how this forum manages to stay afloat with a person like that running things. Never mind the fact that he treats posters like garbage, this is supposed to be a forum for people interested in Japan, it shouldn't be run by someone who is obviously bigoted against the Japanese. And I don't use that term lightly, I've made many posts on here that have been highly critical of Japan. But the tone of that thread and the draconian rules enforced to stifle anything other than virulent anti-Japanese views cannot lead one to any conclusion but that the person running it is a bigot. To give an example of the type of thing he posted:
