The term "whataboutism" is some stupid manufactured shitlib term used by neocons/neolibs in an attempt to obscure jewish misbehavior. You see it from shills on reddit all the time, and hear neocons in the media use it non stop.

So if for example some establishment neocon/libs are blathering on and on about how Russia invaded Ukraine, if you point out the US did worse to Iraq and numerous other middle east countries, or point out Israel routinely bombs neighbors and occupies Palestinians, they bring up this stupid nonsensical made up word whataboutism thinking that will somehow shut down all debate.

So yeah I'm not surprised you'd use the term so you can blather on and on endlessly about the holocaust.
