Just take oxidizer to me an “something that accepts electrons, like oxygen would”. Of course, there’s some oxidizers that can accept electrons from things that oxygen can’t (think of fluorine, for example) but... it’s just a term.

There’s also an enormous continuum of timescales, all the way from the detonation of high explosives, to deflagration of low explosives, combustion of fuels, to... sedate rusting, which is just oxidation of iron or steel. YMMV.
