If you say it wasn't 6 million, you are a Holocaust denier and could be locked up in some countries.
Priceless.
The truth is, yes.
Show me a country that locks you up for saying it wasn't 6 million. And before you start moving the goalposts, read what you wrote.
Austria
In Austria, the Verbotsgesetz 1947 provided the legal framework for the process of denazification in Austria and suppression of any potential revival of Nazism. In 1992, it was amended to prohibit the denial or gross minimisation of the Holocaust.
National Socialism Prohibition Law (1947, amendments of 1992)
§ 3g. He who operates in a manner characterized other than that in § § 3a – 3f will be punished (revitalising of the NSDAP or identification with), with imprisonment from one to up to ten years, and in cases of particularly dangerous suspects or activity, be punished with up to twenty years' imprisonment.[15]
§ 3h. As an amendment to § 3 g., whoever denies,
grossly plays down, approves or tries to excuse the National Socialist genocide or other National Socialist crimes against humanity in a print publication, in broadcast or other media.[16]
Belgium
Holocaust denial was made illegal in Belgium in 1995.
Negationism Law (1995, amendments of 1999)
Article 1 Whoever, in the circumstances given in article 444 of the Penal Code denies,
grossly minimises, attempts to justify, or approves the genocide committed by the German National Socialist Regime during the Second World War shall be punished by a prison sentence of eight days to one year, and by a fine of twenty six francs to five thousand francs. For the application of the previous paragraph, the term genocide is meant in the sense of article 2 of the International Treaty of 9 December 1948 on preventing and combating genocide. In the event of repetitions, the guilty party may in addition have his civic rights suspended in accordance with article 33 of the Penal Code.
