Perhaps both then yeah, I didn't realise that the racism meant Greenskins and Brownskins hated each other, I assumed it meant they just hated anything different from them, like other races. Not sure how I didn't realise that.
A 'peaceful' race of Orcs is a somewhat unusual concept, violent within their own culture but perfectly able to conduct themselves around other races, when they choose to. Perhaps still being xenophobic and yet being able to deal with the 'inferior' races who's ability to recycle scrap is pathetic compared to theirs.
Thanks for helping me out with this, it helps a lot. Editing more now.
EDIT: Editeded.
