Since nobody has pointed out what is wrong with that biography, let me explain. The hint was that I responded to a post about Haredim not wanting to teach about LGBT. The Neturei Karta website has one of the most detailed and accurate biographies on the internet, but with one major and hilarious gap. They say

While training for the teaching profession, he began to attract attention in literary circles. Among the admirers of his poetry was a (non-Jewish) physician, Johanna van Marseveen, whom he subsequently married.

No mention of the fact that a lot of his poetry (and his novels) dealt with homosexuality. This got him into trouble, as the Dutch were not as tolerant as they are these days, but at least they didn't shoot him.

He continued to write poetry along these lines throughout his Zionist and anti-Zionist phases. Here is a sample, from Kwatrijnen

Twijfel

Wat wacht ik in dit avonduur,
De Stad beslopen door de slaap,
Gezeten bij de Tempelmuur;
God of de Marokkaanse Knaap?

"Moroccan" is presumably a reference to the fact that the Moroccan quarter (1193-1967) was adjacent to the Western Wall. There is a monument to him somewhere in Amsterdam, with the following poem by him

Die te Amsterdam vaak zei 'Jeruzalem'
En naar Jeruzalem gedreven kwam
Hij zegt met een mijmrende stem: 'Amsterdam, Amsterdam.

Neturei Karta doesn't mention this one either.
