Your entire comment is complete bullshit and you know it.Gas chambers were discovered by the allies.Examples of such camps would be Auschwitz-Birkenau (which was part-concentration, part-exterminaton camp), Treblinka, Belzec, Kulmhof, Sobibor (which were pure extermination camps). https://holocaustcontroversies.blogspot.com/2017/05/rebutting-twitter-denial-most-popular.html#sovietsandcamps As for your claim that them being jews=they lied(which is complete ignorance because by that logic since you support hitler and the nazis then you can't be trusted with your holocaust denial because its clear you want nazism to be revived.) It is proven by the cumulative evidence of a) the documents (mostly German wartime documents), b) testimonies by people belonging to numerous ethnic groups (incl. Germans, Poles, Ukrainians, Russians), who were perpetrators, bystanders, and victims; https://holocaustcontroversies.blogspot.com/2015/10/contemporary-german-documents-on.html Also your last part is the pot calling the kettle black since you continue to believe this is somehow all lies.
