I know this was a year ago, but I'd like to add on to this, thinking of Ideology compatibility in general.
Alien slavery and cannibalism often come up as "horrible" in Ideologies that hold human slavery and/or cannibalism as honorable and required. It'd make sense if it was a xenophillic ideology, but that's often not the case. If there's no way to make it "copy" the other precepts, maybe the default could be a neutral "acceptable"?
Along with this, aliens often want to- or do- wear hairstyles that are reserved for different races, which can often look funky. Like a cactus growing human hair, or a feathery oni growing a human beard. It'd be nice to be able to disallow a specific hairstyle on specific species in the config menu.
Apologies for the giant wall of text!

To expand on that a bit, I find it a bit weird that the xenophobia meme requires that alien cannablism to be at preffered or required to be a bit odd. Just because you hate aliens doesn't necessarily mean you want to eat them. I think it would be better if you also had the alien cannibalism option of acceptable or maybe even disliked when selecting the meme.

I patched the Xenophobia meme for allow to choose EatingAliens:Acceptable, and patched the precepts EatingAliens and AlienSlavery for make them follow the rules of vanilla precepts, and so have them spawn better in factions ideologies.

But it's still not perfect, because currently the precepts have to work by pair:
_if Slavery is disapproved but AlienSlavery is approved, the pawn will be at same time sad to have a slave, and happy to have an alien slave (with only 1 alien slave in the colony)
_Same with Canibalism, disapproved but EatingAliens approved, will be sad to butcher an alien...

So I still have to set manualy on Acceptable the matching precept when one precept is Acceptable or more, to have an ideology not crazy.

I think the same issue could happen if "Alien Corpse" is added.
