Black, dude, at the end of the day a racist fuckass is a racist fuckass, regardless of who he or she is for/against. Period. End of story.
Except, of course, when there's more to it than just racism. The different metaspecies are different -- quantifiably and truly -- in ways that the real-life races and ethnicities of the world never have been. There's a (completely reasonable and appropriate) knee-jerk reaction against racism, from our modern-day sensibilities...but there is at least a kernel of truth to some of it when it's found in the Sixth World, where metaspecies are concerned.
Even in that case, all they're doing is exacerbating the differences that exist, ensuring ongoing animosity and violence, because they want to keep insisting that humanity should be a Special Snowflake, when we're not... not in the Sixth World, at least.
Yeah, elves are gonna out-live everyone. Bitching isn't going to change that, and nothing anyone can say will convince me the alternatives (aka, mass murder or genetic tampering) are ever going to be acceptable. All it does is give them someone to blame, other than their own short-comings, for the bad things that happen to them in life.
As for the other point... if they're worried about their "precious baby" getting bruised up by the 3-out-of-5 metatypes with superhuman strength, then they should home-school them. Otherwise, let the kid learn how to not piss off people who can make them eat their own nose... a feat which would be a lot easier if the parents weren't teaching their kids to treat the really big, really strong metatypes are "dirty" "stupid" and/or "inferior."
Yeah, I'm sure that being conditioned to talk down to the 6'5" slabs of muscle laced with teenage hormones has absolutely
nothing to do with the the fact that they got the shit beat out of them. It was just the Ork being a big, stupid, raging beast. Definitely.
Now, of course, this is just my personal take on it... but I tend to have the delusional belief that, in the absence of individuals actively trying to stir up drama for their own personal reasons, a group will tend to coexist peacefully. The problem is that, in the real world, you just can't get rid of the drama-queens faster than they breed.
