So the Rwandan genocide killed somewhere between 500,000 and 800,000 people in 100 days, in a backwater African shithole, with nothing but machetes and a few rifles. And you're telling me one of the most advanced states in the world couldn't kill 7-12x that many in 20x the time (1939-1945) with machine guns and poison gas?
Are holocaust deniers just stupid? Do they actually think anyone will fall for their shitty agitprop?
