In my view some people, including me, agree with some of your statements but differ HOW you express them.
From my culture (not very different to yours) you sound quite rude sometimes. I guess Nick G is not apologizing, he is probably trying to express what you said in a very polite way to make this forum a better place.
However apologizing is a good behavior (even if you think you might eventually hurt someone) and we should do it more often when needed.

PS I won't apologize to you beacuse I'm sure I didn't offend you
