As the old saying goes, 'Freedom of Speech ends when your fist reaches my nose', when someone starts saying that pregnant women should be screened for 'defects' such as gender-assignment, I do start to worry, because that's an incredibly slippery road.
For example, there's an easy way to get rid of the racism row in the US, you could adjust fertilised eggs so that all children born to any parent was white, that way, no race problem, but, not in a million years, would people consider the gains worth the cost. You need to stop and think very carefully before talking about screening children, some things, like hepititis etc have a direct impact on the persons ability to live a normal life, and, yes, I could accept defending against those, but others, like the existence of Transgenderism, racial characteristics etc, do not effect the person's ability to live a perfectly normal life depending on social acceptability, it's other people that are the problem.
There's a motto in Medicine, which states "Above all, do no harm", fixing transgenderism etc is not something which needs to be done for the person to be healthy, it is unneccesary surgery, and actually goes against the Hippocratic Oath.
Society is faced with two choices, either it can change and stop attacking the different, or it can force the different to conform, either socially or medically. One way is progress, the other is stagnation.
