Presumably then you are against all genetic screening during IVF or pregnancy and consider it to be “eugenics”?
The argument that you appear to be making is that we should pretend that science and modern medicine don’t exist and instead deliberately enable children to be born with painful, distressing, life-limiting and life-shortening conditions.
You appear to view their suffering as collateral damage because you fear state overreach. In my opinion that is always a risk and why democratic societies must be active and vigilant and continuously hold their leaders to account.# The answer is not to inflict preventable suffering on babies and children to use them as a human shield to protect your own rights and freedoms to do have children in normal circumstances. I think that is morally unacceptable and clearly not an appropriate basis for policy. It is reminiscent of the arguments that some made against assisted dying being available for people with terminal diagnoses and pain that cannot be alleviated and who face horrific and frightening deaths, and that we should continue to force this on them because other people are scared their own unrelated rights might be eroded. Like the babies born with genetic diseases, these terminally ill people have no choice and it is not right for others to deliberately inflict this level of likelihood of suffering on them when it’s completely avoidable.
It is not remotely comparable to compare higher risks for, say, older parents to the risks from cousin marriages because:
Firstly the risks from the latter are cumulative, and much higher anyway when you compare the data properly (despite the clearly politically motivated misinformation campaign pretending that they are comparable);
Secondly, all rights exist in a balance against how much they infringe on the rights of others. Banning cousins marrying would not prevent the people marrying cousins from having any children at all, which is what you’d be doing if you said that anybody 35+ can’t have children. Given the risks of the former are much higher and compound over generations and are completely avoidable without removing anybody’s right to have children, the balance of the rights of the child and the rights of the parents to do what they want is clearly heavily weighted towards legislating against this practice;
Thirdly, banning pregnancies for people over 35 would necessitate and legally require abortions because some pregnancies of course happen accidentally even when using contraception. If cousin marriages were banned it would give legal standing to the natural aversion to and taboo of inbreeding and as a PP noted the communities primarily engaging in this practice generally don’t have babies outside marriage so the numbers would decrease significantly. We cannot base policy on the fact that a few people might be prepared to engage in criminal behaviour: that’s an argument for enforcement, not one that should affect policy making. Banning actual pregnancies would be eugenics. The law proposed is not stating that if two people unaware that they were cousins had sex and conceived a child that child should be aborted.
Fourthly, we legislate all the time against harmful social behaviour. All laws must balance the rights of the individual with the rights of other people who may be impacted by their actions directly, and indirectly (e.g. the impact on wider society through the funding demands on the NHS). Life is not black and white, it is nuanced and judgements have to be made in the cultural and scientific context of the time. In this case many children can be protected from suffering avoidable harms without restricting anybody else’s rights in an unreasonable manner that would have any negative impact on their life, given they have 4bn other opposite sex partners on Earth to choose to marry instead who aren’t close relatives.
#Things like not voting for parties who are pledging to abolish human rights charters would be a good start.
