I find this "You can't blame Germany for supporting genocide, because they're guilty about the Holocaust!" defense kind of hard to believe. After all, Germany also committed genocide against the USSR, and yet "Russia delenda est" seems to be an extremely mainstream position among Germans currently.

It’s easy to criticize the West for not taking a stand against the genocide in Palestine

Actually we're criticizing them for actively supporting the genocide.

we do not, and can not, understand what Germans (in general, there always exists some racist fascists in every country) have to overcome to take such a stand.

This is incredibly tone-deaf, given what people in Gaza are actually having to overcome.
