I don't know, I think it kinda depends on how you look at it. Sure oxygen doesn't burn without a fuel source, but a fuel source won't burn without oxygen either

I don't know, I think it kinda depends on how you look at it. Sure oxygen doesn't burn without a fuel source, but a fuel source won't burn without oxygen either; both are required in order to produce fire. Why do we then say the fuel is burning but not the oxygen? Just a thought...
