I don't really care... they are just missing out on good music.
I never liked them myself.
But I just realised that they are just like any part of music, a way to present and emotion, I realised they were an intergral part to metal, and I just got used to them.
A lot of Death Growls are similar, scratchy, and the reason I love Mikaels so much is because he is really deep and smooth. He's one of the best. I still like all other growls though...
Maybe people need to look at it that way...
