So if an alien race far superior to our own arrived on earth tomorrow and started having humans for breakfast, just because they were tasty, you wouldn’t object right?
If they're smart enough to subdue me and my entire civilization using technology unfathomable to my puny human mind then I guess I don't really get a say and it doesn't matter what I think anyway, now does it?
There's an analogy to livestock in there if you look hard enough.
So if intelligence is the marker, is it ok to manipulate mentally handicapped people?
We're not talking about marginal intelligence difference. You're making the exception the rule. We're talking different species here. The food chain applies and if you're not at the top there's no advocate built into nature for you. You're a commodity and the only thing securing your survival is your value and the responsibility of the species above you.
Of course I would. Do you think my lack of objection somehow shows a moral inconsistency? I think you do -- but that's only true if you project a very rigid and symmetrical concept of moral intuition on to me, which I promise you I don't hold.
