So this is how it usually goes:
StarFleet: You Aliens look like you need our help!
Aliens: No we're fine! Please leave.
StarFleet: But we really want to help you!
Aliens: No thanks you. You can go now.
StarFleet: Awww c'mon. Let us help!
Aliens: No. We're good. Please go now!
StarFleet: We're not leaving until we help you (big smiles)
Aliens: JFC! Fine whatever!
It's want I call the 'Dr. Quinn Syndrome' which translates to "Look Indians! Let's help them!" But in this case of course it's "Look aliens! Let's help them!"
What these people are doing or how they got there is no one's business but their own. Certainly not Captain Archer's or anyone else in StarFleet. Some people seriously need to learn how to take 'NO!' for an answer and go away.
Maybe the Vulcan's were right about them. They are not ready to be part of the intergalactic community if all they do is annoy the people they meet.
I'm sure its some sort of Narcissistic behavior.
