Again, look at what you wrote: "If they are sane they can't" [have the right to commit suicide]. "If they are mad, remove them from the gene pool."[via suicide?] This OBVIOUSLY has the broader meaning that 'mad' people can and should be 'removed from the gene pool'. Anyone reading your comment understands that you think people who are 'mad' are not valued enough to be prohibited from killing themselves.

Hence my responses.

You've found the Aktion T-4 euthenasia program, but you conflate this with my comment about concentration camps, which included the Aktion 14f13 extermination program. Look again and you'll see that what we call 'concentration camp' is broadly recognized as detention and extermination camps that were related to Aktion T-4 and 14f13 extermination programs (1934-1945). Mental illness victims sent to BOTH of these camps were often listed as 'disabled'. "Historians estimate the total number of deaths to be 11m, with the victims including gay people, priests, Romani people, people with mental or physical disabilities, communists, trade unionists, Jehovah’s Witnesses, anarchists, Poles and other Slavic peoples, Black people and resistance fighters. Half of the victims who weren’t Jewish were Polish." Other victims were dwarves and African-German children.

Between 1939 and 1945 an estimated number of 300.000 mentally ill and handicapped people were murdered in the German dominion under the pretext of “euthanasia”. “Aktion T4” and “Aktion 14f13” are the best known aspects of this politics. The article describes the history of the idea of “life unworthy of life”, its radical and cruel realization in the German Reich and its occupied territories in the era of National Socialism; it differentiates between the various forms of action taken in the context of the “euthanasia” program, describes the perpetrators and their motives and attempts to commemorate the murdered individuals. https://www.sciencespo.fr/mass-violence-war-massacre-resistance/en/document/extermination-mentally-ill-and-handicapped-people-under-national-socialist-rule.html
