Troll? Hmmm
Never saw the need to slate bands, after all, it's personal taste, and what has it got to do with anyone else what somebody wants to listen to?
Not defending Sabbaton as I haven't heard anything by them, but I'd never wish harm of any artist, from Bieber to Cannibal Corpse. Variety is the spice of life, and without artists we don't like, artists we do like would not be around as they'd have less to rebel about.
