Battleragers aren't supposed to be nice tea party guests. They're supposed to be bloodthirsty killers. Every single one of them. They're not like fortress who would rather convert people. Ragers are more violent and just want to destroy magic and mages. Not to say they can't be different within that tent, but it's absurd when people get upset that villagers aren't nice to them after they're killed or otherwise not another battlerager.
