These intolerant people don't want people who aren't like them to even exist, much less accept them as a normal part of society. They are happy to ignore sex chromosome differences they can't necessarily see like YY, XXY, XXX, chimeras with multiple sets of genetic information, etc., while placing their own ignorance over the consensus of scientists, doctors, and psychologists. It's not much different than racism, really. Just another way of othering.
