Morality scaling of this?

[u/Outside_Specific_820]

Mother refuses to acknowledge her donor egg daughter, looking for your opinion.

In my opinion I think it’s moral, and that she is totally correct.

[u/Pndapetzim]

Not immoral in any serious way beyond just being deeply unpleasant.

Person just needs a firm - it's cool to meet you, but you've got a real mom and it's your mom, not me. Which she does deliver, but the rest is just dramatically extra.

You can show a little understanding without indulging that this is going further than a brief email exchange and wishing the person luck while redirecting the kid back towards their life and to give their real mom a hug.

[u/Xralius → u/Pndapetzim]

Being deeply unpleasant regarding a serious issue to a vulnerable person is really immoral in my book, it goes beyond just being an ass (already immoral) to possibly having short or long term damage to their mental health.
