But when you are making an apology or when someone is angry at you and giving you a lecture, you should often look at a lower point with your head slightly down.

1. I think Japanese people feel ashamed or scared when they are looked in their eyes.

2. I'm offended by direct eye contact in certain situation. I know eye contact is important. But too direct eye contact makes me uncomfortable. You should keep from staring.

3. Japanese people don't look at someone's eyes while they're talking with someone. Foreign people think it's strange. But it is a gap of custom.

4. Japanese people are not accustomed to looking at eyes while talking.

Your English is very good. I did not find any important mistakes in your answers at all.But let the native speakers comment better.

Even without the belittling tone, I think it's not polite to comment on someone's language skills, positively or negatively, when it's not asked for. I can see that the "looking forward to your comments" could be understood as a request to have the language reviewed, but I would have thought there's something to say about the content too and not just the amount of mistakes!

I doubt if the stars were as offended as you Scandinavians were...but of course only the stars (and yummi) can tell us what was actually intended and what the reaction was.
