I'm surrounded by holocaust memorials, in the city where I live. To me, reductio ad Hitlerum appears childish enough almost every time it's used, and it is disappointing to see people argue thusly while cheerleading for those who chose not to take a safe and effective treatment against an illness that has so far killed about 10% of all civilian and military deaths in WW2 combined, or 50% of the especially infamous genocidal deaths.
It's not like the people who genuinely couldn't take the vaccine benefited from any of this.
