Biologically, there are only two genders: Male and female. It is facts. It is science. It is evolution. It is indisputable. It is not open to interpretation. It is reality. Intersex you may ask? A genetic anomaly not different from being born with two heads.
In fact, there are at least 2,000 identified genes that separate males from females. Gender biology is also very specific, with each gender being drastically biologically different.
Transgenderism is an invention from feminists and the radical left to emasculate and neuter as many men as possible, so those men are brought to their level, and women can finally pretend to be what they biologically are not: Equal to men.
Transgenderism, however, remains a mental illness. There is something fundamentally wrong with wanting to cut off your balls, slice your dick inside out to try to make it into a pseudo-vagina, and take hormonal treatments for the rest of your life with devastating effects on your health and the environment (ever wondered why male fishes are mutating into females?)
Societal acceptance, or mass hysteria about it would be a more accurate description, means nothing. Society has accepted other abhorrent concepts in the past, from communism to nazism.
