Stay.
Don't concern yourself about not being a "space nut". The other boards such as Current Events and Off-Topic have a life of their own and provide a setting for discussion for all.
Forgive the distrust. Some of us still sting from realizing we can't even trust our own government in the case of Iraq. Also there are plenty of people here that could be posing as you with the intent to make fools of us.
In the end, your words and length of stay here will prove who you are.
