Well, sorry, but what are you saying? I sound a bit frustrated but I did ask you to clarify whether or not you were making that comparison with respect to the categories described in the previous post, precisely because I thought it would be very odd to say that donor-conceived children were worse off than the children of drug addicts.
Not to be rude - genuinely - but did you perhaps misunderstand me, or lose track of which post you were replying to?
Obviously, like all parents, I think it's interesting and useful to consider how we could be better. But I think that is very different from breast-beating about things we can't sensibly change. Yes, it'd be lovely if we all raised our children in happy, wealthy, well-educated two-parent households: but how is that useful to a single parent now? Yes, you might regret choosing an anonymous donor, but honestly, if at the time you went into that situation thinking you'd done your best, then I don't think you should beat yourself up about it endlessly. And I think you should expect that your medical care would be what you paid for.
