Not the person you're responding to, but: They may want to learn to communicate honestly. I would find the situation described deeply irritating. Enough to cut contact for a while, even.

Yes.

> Should we abort fetuses who have some disability?

If the parents are unwilling or unable to deal with it every day for the rest of their life, yes.

> I'm sure that any of those individuals, once born, would prefer to live regardless of circumstance.

That's too big an assumption. But, in any case, not being born, and not having a working brain capable of abstract thought and understanding of the situation, nor a way to express it, they don't get a vote.

What else can it be, if not a part of the mind of a state of it?

A little weak, though. I'd rather have something more impressive, like the message embedded in the decimals of Pi as found in the Contact novel. (That also doubles as an argument to present to believers: "if the real world had something so concrete and verifiable in the real world that could only have been inserted by the creator of the universe, that would be an actual reason to believe that such a creator exists. In the mean time... please don't".)

And that's actually a problem. For them, that love for a fictional character that for them is real is, in many cases, more important that the love for real people. For whatever reason.
