You’d rather not know

The aliens are much like processed junk food, cheap "fast fashion" clothes, and Apple products, at least in one respect: it's much easier to be happy about them if you try to forget under what circumstances and by whom they were created.

If confronted with the truth, I recommend responding as you would to information about unappetizing additives, sweatshops, and suicide nets: simply plug your ears, close your eyes, and shout "la la la I can't hear youuuuuuu" until the person disturbing your blissful ignorance kindly shuts up and goes and fucks himself (which, incidentally, is how the aliens reproduce).
