Bingo.

How do any of my fellow biology experts put up with this bullshit?

Sure, there are some rare genetic anomalies, and sure, there is such a thing as epigenetics which can effect some phenotypic outcomes, and sure, some genes that affect your brain chemistry & have a tendency go along with the genes that determine sex & other related genotypes will not follow the trend... But those are often subtle or minor in comparison to everything else contributing to your sexual makeup including your XY chromosomes.

But even if you have a severe case, none of that changes your base sexual genetic makeup. Either you have a Y in there somewhere or you don't.

Spez: Not like progressive engineers aren't trying to get rid of it, though: https://www.google.com/amp/s/theconversation.com/amp/the-y-chromosome-is-disappearing-so-what-will-happen-to-men-90125

But even if the Y does eventually degenerate as they are speculating in that article, the sex genes have to go somewhere, and that somewhere becomes the new "Y" gene.

Trying to remove it and insert it elsewhere to appease some lesbian couple will result in unforseen issues that only hurt the engineered child. And even if they could "perfect" that process (unlikely, as things are so interwoven & complicated that humanity will likely never figure out God's blueprints), in order to do so, they would have to do an ungodly amount of abusive experiments first. You can't be the "good guy" in that scenario no matter how much you try to claim that the ends justify the means.

Point stands, it doesn't matter if you have XY or XXY or XXXY or XXXXY. That Y will give you male characteristics you otherwise don't have, whether they are obvious or not. Genetic engineers trying to futz with it and play God will only end up abusing life. Probably where all that "garbage" stem cell & fetal tissue (a.k.a. unborn children) PP sells is going to right now... Genetic & biological experiments at the expense & abuse of life.
