Agreed. If the only way you can beat the guy is by trying to disqualify him based on a technicality then your position is pretty weak. Try attacking his positions and his record, not his imagined religion and his imagined nationality.
Yup.
Edit: PEople come in all the time bashing Obama. I stop them and ask if they even know why they hate him. usually it is "becasue he is a democrat" or a marxist or a communist or even muslim. At that point I tell them to go back to not thinking.
