Look, you're clearly very bright. And you have a good mind but take a little advice from someone who's made it through to the other side: fighting with your professor? Not helpful. Whether they're right or wrong, you didn't only waste your own class time but you took a lecture away from all the other students (who are also paying for their educations). If I'd have been in that classroom? I wouldn't have waited for security to kick your ass out the door.
Next time try having that debate in private, maybe.
On the other side of things, I do admire your unwavering dedication to the truths you hold important. Don't ever lose that.
