There are only two genders

Hey, acutally your point is wrong.

The gender spectrum is an understanding that gender is not binary, but rather a spectrum of biological, mental and emotional traits that exist along a continuum.
In contrast, the gender binary—also called gender binarism or genderism—is a belief that gender is composed of two distinct and opposite genders (women/men) in which there is not overlap.
Unfortunately for those who believe in a gender binary, it is not scientifically or medically correct. Gender can’t be binary, because it is a personal identity and is socially constructed.
Sex, which refers to one’s biological characteristics, also exists as a spectrum, because intersex people exist. A person’s sex can be female, male, or intersex—which can present as an infinite number of biological combinations.
Today, numerous scientific fields, including biology, endocrinology, physiology, genetics, neuroscience, and reproductive science, have confirmed that both sex and gender exist as a spectrum.

-- Closing Statement

When using the terms sex and gender, it is important to note that “sex” (female/male/intersex) describes biological traits. In contrast, “gender” is a broader term that reflects how a person lives within society. One’s gender identity could be woman, man, transgender, nonbinary, or an infinite number of other possibilities.
Because gender is a personal identity, is socially constructed, and has limitless possibilities, it takes no further explanation to explain why it is a spectrum.
Therefore, when people question the existence of a gender spectrum, what they are usually questioning is the existence of a sex spectrum. 

I know that this biological statement is considered critical in today's society. However, it does not matter; society is constantly changing. Today's society in Western countries has become very effeminate: 60 years ago there were clear role models for men and women. These are softening nowadays, so that the social differences between the two sexes have become smaller. Just because role models have faded into the background, however, does not give us the ability to adopt or invent new genders. The many changes in society make them questionable. But what is fact remains fact.

Okay Gendermatico, I see you're seriously trying to break my points - but once again, you are wrong!

Let me explain why (and yup, lets talk biological gender):

- That is scientifically wrong.

- Just because some members of the forward-headed LGBTQIA+ is not able to reproduce is no evidence for them to not exist.

- Party, non-binary persons are actually able to reproduce:

Artificial reproduction allows the LGBTQIA+-community to theoretically increase in population and and brings them up from their biological capabilities to a common level.

... and let "facts remain facts":

- No one "invents" new biological genders, since evolutionary mutations and adjustments to nowadays technology (referring to the European Sperm Bank and other methods of artificial reproduction) have simply put a gap between male and female.

--- Closing Statement

There are more than two genders, because:

- not being able to reproduce does not proof non-existence of a gender

(- non-binary genders can actually reproduce)

- biological mutations

- your 99.8% binary at birth is wrong (non-binary gender is often not visible from the outside. if so, many affected people feel pressured to keep that circumstance secret).

But what is fact remains fact.
