@arya: "Don't shoot the messenger"...hmmm...I would generally agree...however, the messenger is responsible for how the message is being brought across. And sometimes that makes all the difference! Unfortunately a lot of folks seem to forget that when postign in forums and facebook etc.
There surely is a difference between a) truly and openly discussing things in order to learn together (you may also find out that you were wrong in that discussion...or not) and b) to just talk down on people.
I agree that one should try to convey the message in nice manner and not try to put people down deliberately, but written conversations can be difficult at times and easy to misinterpret, since we have nothing but the written words and how these words sounds to us in our subjective mind.
That was a long sentence, sorry about that

I hope It wash´t totally confusing.
Anyway, we have no expressions or body language, etc. to help us here.
There are so many different personalities here, and many of us don´t necessarily communticate in the exact same manners as others see as the "correct" and only one, at all time. That doesn't mean that the intentions behind the posts is bad, even thought it might be interpreted like that to SOME of us. Just because somebody´s not rubbing your back doesn't mean that they are trying to put you down.
So, how some of you interpret the posts from certain others in the is thread is very different from how others might interpret the same post. f.ex (just an example!) You might find the post to be subduing, whilst I don´t.
In this case the information seem to hold water, doesn't it? Or have I missed out on something? How about just saying "Oh, I wasn't aware of that. I´m going to look into that. Thanks for giving me the heads up!" Instead of starting insulting, or even try to put down these people that gave valid info, just because you interpreted their posts as down putting (or false).
And yeeees, I know I should follow my own advise sometimes....
