I'm sure Kirk really cares.
"Oh please, guitarist from a borderline irrelevant B Grade hair band, don't hate on me. Now if you'll excuse me, I'm going to drive my 24k gold helicopter downtown, purchase the rights to your entire catalog, and have it destroyed to erase the shred of a memory that most people have left of you..."
I'm not knocking Reb, but it's completely tasteless to badmouth a fellow guitarist. It just makes Reb look that much more butthurt that Kirk is getting recognition for his body of work than he is. There's a lot more to being a musician than being a technically proficient guitarist, and Kirk has more widespread influence than Reb ever will have. There's more guitarists that will pick up a guitar now and be inspired by Metallica and Kirk now and 20+ years from now than ever will be for Reb. Most young guys picking up a guitar these days have never even heard of Reb, but I bet they all dicked around with the main riff to Enter Sandman or learn some Kirk solos along the way.
It's like Hendrix, the man could be the sloppiest live player you've ever heard and he wasn't the most technically proficient, even for his era...but you can't deny his appeal and the inspiration he gave that made countless guitarists we love these days pick up a guitar to begin with.
