Do you think marching band is a sport?

I don't think I have ever heard a good argument for this one. I have been in it and I know that it's hard, but so is getting a 2400 on an sat or painting the fingernails of your dominant hand. Difficulty really isn't a good measure of what is a sport and what isn't, so can I get some good arguments please? And none of this "we practice more than any other sport" bullsh*t. I know you do, but that's only because you're not working as hard. Think about it, some honors students study for 5+ hours a night in addition to school. So why do you think it is? Or isn't?
