My advice would be to do what you can live with.
If you have the time and energy to appeal a potential bad grade, I say go for it. Write what you believe in.
If you just want the grade without any hassle, write it how you already know they want it. It is just one paper in your lifetime. And you know what you believe in, so who cares.
But I know that some people just can't live with that, and I respect that as well.
This may sound bad. But if it were me, I know that I wouldn't put the effort into fighting the bad grade. I would consider it an "opposite paper" and I would write what I know would get me the grade I want and out of that class.
