Ok, my two cents:
If you're concerned that your gf might regret a tattoo later in life (laser surgery is expensive!) or she's being to rash about it now, then I agree that you should probably ask her to hold off on it and see if she still wants one in a year (and stop making excuses based on your religion for it!). In the end, you have to let her be the person she wants to be. If you're not comfortable with that person, then you're not right for each other.
If this really is just a religious reason, then you're beyond help anyway.
