Are you kidding me?
Are you stating that simply because 'the majority' of the community says they don't want sprint in the game (CITATION NEEDED) that it isn't an opinion anymore?
You're wrong. While it could possibly be a highly supported opinion that many people back, it doesn't make the statement 'Sprint doesn't belong in Halo.' fact. I don't know why you think it does, but it doesn't.
I know many people that like sprint, and they are Pro-Evolution for the Halo series.
"Sprint doesn't belong in Halo!" is still an opinion, no matter how many people support it.
