Gender identities — catalogue of an ideological belief

A catalog of 25 self-invented "gender identities". The proliferation is not progress in knowledge but proof that gender identity is a creed — without a marker, without a test, without proof.

Why a catalog?

Anyone who Googles "gender identities" finds lists of 30, 60, sometimes more than 100 categories. On this page, we document the 25 that circulate most frequently in a Dutch-language context — not because they have scientific status, but because they are common in information, support, and education, and cause harm to children and women there.

The catalog itself is an argument. When a concept branches out from two categories (man/woman) into dozens within two decades, primarily via Tumblr and TikTok without any clinical or biological anchoring, that is the formation of dogma. The underlying construct is unfalsifiable : there is no criterion by which a new category could fail. Anyone who criticizes is silenced and dismissed as "hate."

For every identity, we use the same lens: what is claimed, where does it come from, what is actually known, why does the concept not hold up. Consider the circular reasoning underlying every definition, self-reporting as the only "evidence," and the explosive spread since 2010 via social media ( Littman/ROGD ).

What this means: a faith without foundation

The list grows every year. Every new category is justified by the existence of someone who identifies as such — which is true by definition, because the identity is constituted by self-reporting . There is no measurable marker , no genetic marker , no brain marker .

A scientific concept can be limited: there are conditions under which it applies and conditions under which it does not. "Gender identity" knows no such conditions — it is a creed. Anyone who reads the catalogue consecutively sees how the dogma cancels itself out through endless refinement while simultaneously remaining immune to scrutiny. This belief justifies puberty blockers, mastectomies in healthy girls, and the wiping out of the category of woman.
