Like Asmodeus said - try to lean towards the intent of the site, not the individuals - or yourself.
Trying desperately to change to fit in with NT's is a futile attempt, just the same as if the Nt's were trying to fit in with you, it ain't gonna happen. But we Can get along.
If I am focusing on the NT, then I am ignoring the person, and anything that person does or says is already subjected to my focus. However I can't take all the blame and shame, Nt's do the same thing, just like you stated in your original post, they were focusing on the personal differences, therefore blocking anything or any input you might have, other than that difference they choose to exaggerate. Deal is, it's not a racial, social, religious or any other limiting group that these things apply too. It's an individuals actions, not the entire country they are from.
Thing is, nobody is perfect regardless of such claims. We all have good and bad, strengths and weakness, which ever one we feed or allow to be fed, will be the stronger of the two. If I feed or get fed negative crap, same effect. So as was already said, feed the good, for good, with the good that we all have in us, and it will all be good. If you are trying to change their opinions or actions, it will only entice more fear that you might be right. If you set an example of bashing and flaming and so on, guess what.....And to reverse ones opinion of you, it takes seven times as long as their current opinion has stood, so you might want to consider if it's really worth it.
