I think I'm the only person who thought "I wonder if the Predator is even male or some alien gender". Trying to think of it in terms of human ethnicity never occurred to me once I was dwelling on its possibly foreign reproductive processes. (I -think- they've since shown Predators with boobs, implying at least lactation and nursing (or a weird psychological hangup with mammaries), but that could still be something the "male" does, because "alien organism".)
Just in the expanded universe created collaboratively by companies licensed to produce comics, novels, games, and merchandise. The movies never mentioned any sexual dimorphism. The predators seen in the movies may very well have included females.
But you will almost always support one side and deny the other. This I find is where this falls into intelectual dishonesty or incompleteness.
As I said, 'Gut' is a awful measuring metric for what is 'OK' or not.
I know I pinball a lot. It's not fun.
Then historical roleplaying is out, and anything based on historical roleplaying is out, meaning you're left with fictional creations that lack any real grounding. They'll tend to be superficial reflections of the modern world. So your choice is between creepy and vapid.
Is it? I mean, nowadays we know colonialist sentiment is... well, I personally don't support colonialism. But that doesn't you can't roleplay someone with different morals than you. Even if you think the historical colonization of the Americas was horrific, that doesn't prevent you from playing a colonists going around happily massacring the natives.
I can't stop people from playing Manifest Destiny, and I don't want to. That would be unethical. The moral quandary for me is that the acts of colonialism depicted in fiction are unethical, but denying people the freedom to create and play is also unethical.
People should have free speech and therefore the freedom to depict fictional events that are unethical.For me, othering is simply not within my comfort zone. I can depict a complex alien society that engages in horrific atrocities, but I can't go the step of othering them. I can write characters who other them, but I can't as an author with authorial authority do so.
So I can't write a story where orcs are subhuman and therefore it's morally justified to enslave and/or exterminate them. I can write orcs as being born from holes in the ground as adults holding weapons and driven to destroy civilization, as conquistadors from another world who treat humans the same way colonists treated natives, as a lot of things... but I refuse to enshrine colonialist rhetoric into my setting's law of physics.
I could totally write stories where the protagonists are colonists who go around murdering and raping the natives, but as the author I'm still going to consider their actions horrifically evil.
