"Their are only two sets of chromosomes XY and XX and that's it."

Actually there are also XXY and XYY chromosomes and they come with a plethora of problems.

Actually there are also XXY and XYY chromosomes and they come with a plethora of problems.

These are called "birth defects". Just as we should not change the rules just because someone was born with one arm, or three arms, we should not change the rules for other birth defects.

There are only two sexes, male (XY) and female (XX). Everything else is a birth defect at best.
