Will my tattoo cause me not to be accepted into the Marine Corps?

I have a tattoo on my back between my shoulder blades. It is a cross with the American flag in it. My recruiter said that I will get DQ'd for it. However, I looked up the regulation for those trying to join the Marine Corps and it said as long as it doesnt show in PT gear and isnt racist, sexist, gang affiliated, anit-religious, or anti-American than I will be fine. This was a article that came directly from General Conway, Commadant of the Marine Corps. Was my recruiter right, or is what I read correct? I also should add that Im not enlisting, rather than going to college and going through NROTC and becoming an officer.
