is it really neccessary to be that arrogant to a newbie, who tries everything to get some simple help of us?

arrogance?

What about that he about 3 posts down were asked "which derivative" and never bothered to answer? is that not his arrogance?

Erik, you don't know how much I honour you, really. But relationship to absolute beginners and newbies looks to me some strange. It's not only help you give to them, but often punishment.
Yes, i give 'punishment' when two things occur
a) a question to the poster is not answered, but some other drivel comes up - and
b) when a suggestion is totally ignored such as Waquars low port pin that was told wrong oh about 200 posts back and still has not changed.
