Should note that according to Wikipedia (wrapped into a condom: https://wikiless.northboot.xyz/wiki/Legality_of_Holocaust_denial?lang=en ) the only reason why it's not "illegal" in the Netherlands, Airstrip One, Ausjailia, and CHAINA!! is simply because they don't have to make it "illegal", as they can simply lump it into some other artificial "law" regarding "hate speech", which is a fake word with no meaning.

Apparently, it used to be "illegal" in Spain, but people there actually challenged it in court, and it's no longer "illegal" there.

And apparently, Brazil and Ukraina have already passed bills or are pending a pass.
