Kobayashi,
I didn't participate in the threads where you were catching flak. When I first joined this group I made a few mistakes and was a little snotty to one member. As a result, some of the members here took me to task for it. I was a little miffed, but rolled with it.
In reviewing your posts, you obviously are a young and very opinionated fellow. Your statements were in some cases judgemental, even inflammatory.You are just getting into planning, so you are a little naive about what planning outside of academia is about.
Your comments about public education, for example, I disagree with. I believe public education is the backbone of our society. Public education is one of the best things America has. We institutionalized it long before the majority of the world. I attended private schools in the South from elementary school to high school. Perhaps I gained something from it, but I also did not benefit from attending school with like-minded people. Public education exposes you to a wider spectrum of people.
That said, it is just my opinion. As what you said was your own.
Another lesson I learned is just because someone hear disagrees with you, even harshly, you do not have to respond. This forum is like everywhere else in the world. Sometimes one or the other of us acts inappropriately, or is just damn cranky. Let it go. Everyone is wrong some time. Everyone!
There are lots of great folks here. Some I like more than others. I've had disagreements with a few. We get past it.
Don't take it too personally.
One last thing, something I've learned. After you write your post, read it. Think about it. Before you hit "send", make sure that is what you want all of us to respond to. I've learned to rewrite some of my comments, so they are more to the point and less likely to piss people off.
My two cents.
