While I disagree with what TDS says, I will defend their right to say it.
This is a terrifying development that domain registrars are acting as censor, and stating that certain types of content can not even have a domain.
This is the beginning of the slippery slope, because in every other realm of the Internet, we have seen this behaviour. It starts with "Hate speech" but very quickly the scope creeps and we have all manner of things being banned, usually by a very narrow and vocal group of far left / Marxist / Social Justice types.
Unless registrars are presented with court paperwork demanding they take down a domain, they shouldn't be touched.
PR / Business reasons is just a cover for censorship.
