This is a really interesting and worrying area.
Firstly I disagree that a law that should prevent harm should ever fail due to concerns over ‘racial profiling’. The right thing is the right thing, and some things are more important than causing offence.
Secondly, given the number of gender disappointment threads on here, and the fact we can now pay for the NIPT from week 9 of pregnancy, I suspect far more ‘gender selection’ abortions happen than we think - we will never know the true number.
Thirdly, I don’t think this is just an ‘Asian’ thing. There seems to be a strong culture in white women of wanting girls, to the extent I’ve read threads where women sobbed when finding out they were having a boy, or say they ‘can’t love their baby as they could only love a girl’. This seems to be getting worse over time, and I really think gender selection IVF and similar will become more commonplace (abroad) as women fly from the UK to ensure they ‘get their girl’.
Fourthly YES it should be illegal, for r the good of humanity frankly. We simply cannot encourage a human race with a large gender skew, it would be hideously problematic as China found out. It’s also extremely unpalatable to the extent I don’t think it’s compatible with a civilised society. Disabilities are different - they have a huge impact on the parent, far beyond that of a ‘typical’ child. The sex doesn’t.
