You've been hanging out on the Black-Sabbath.com forums too long. They've poisoned you with shitty ideas.
I already told you, the only reason people call those bands metal is because at that point, when they were new, metal was in its infancy and hadn't found its identity yet. People were calling bands "metal", when they hadn't even figured out what metal was and wasn't, much less what bands to call it. Genres evolve, definitions evolve, this is fact; and people eventually realized there was a line separating bands like The Who, Steppenwolf, etc, and bands like Priest, Grim Reaper, etc, because claiming they're even remotely from the same genre is ridiculously stupid.
tl;dr version: You are using an antiquated, antediluvian definition for what constitutes metal, and gtfo with that shit; nobody seriously believes what you're saying other than geriatrics who don't know any better (and apparently impressionable 16-year olds also).
