Dude,
We don't mean any offense. (Well, some of us don't - I only speak for myself !) But you need to understand that we're a little more seasoned group than what you may be used to. A lot of the issues we help people to solve deal with stopping hackers and preventing unauthorized access to their machines. When you come in and ask us to help you do this, we tend to respond emotionally.
The words some of used may have been a little harsh, but the message we are trying to send to you is something we feel very strongly about. You should too.
