Most glam is ok, definitely would prefer it over modern rap or country if given the choice. Symphonic is probably my favorite type, with doom, stoner, progressive, and death all being really close.
I don't think anyone actually said it's not metal. That was just you trying to start up a fight about it.
I'm sorry I gave you that impression. I just wanted to know why and not start up a ruckus about it. No-one has to answer it if they don't want to.
