My name is bigfootkit, i've been a Heavy metal fan for 30 years and a geek collector type for most of that time too, and although i remember seeing ads for Savage Grace's records in the press at the time, i never heard them until about 3 years ago.
(Bigfootkit is impaled on a stake and pelted with rotten fruit by a baying mob as they chant "Your Steel Is Not True".)
Stuff arrives in peoples lives at different times in different ways. To slate a young band by questioning their knowlege of the genre seems like you're trying to catch them out on a technicality. If the band sucks, they suck, but to hold their lack of musical knowlege against them does seem like snobbery to me.
To my way of thinking, there probably should be a "Corroseum Centre Of Metal Excellence", where we can send all those shitey emo bands for reprogramming, but if everyone in young bands only knew the same bands then the chances are, they'd all turn out sounding the same. Maybe their lack of knowlege of Savage Grace can be of benefit to them musically, helping them to find something unique of their own to put into the music.
I've never actually heard Striker, are they any good?
