Yes. Who’s going to tell you that the black swastika in a white circle in a red rectangle was the official flag of Nazi Germany’s government? This is the flag “under which atrocities were done”, i.e. under which the Holocaust happened and under which Germany plunged the world into WWII. If your argument is that this isn’t “a flag under which atrocities were done” but rather “a flag that represents the reason behind those atrocities”, then why doesn’t the hammer and sickle represent the reason behind the Holodomor? Behind all the other extreme atrocities committed by the USSR? Otherwise, if your argument is that it is a flag under which atrocities were done like the hammer and sickle, and you’re saying the hammer and sickle are fine to fly, then what’s the difference with flying the flag of Nazi Germany? I don’t think either of these despicable flags should be flown, to be clear, but I’m asking why you take exception here based on your own argument (or, if you don’t take exception, what the hell is wrong with you).

Basically what I’m saying is that your rationale of “having a flag under which atrocities were done, vs having a flag that represents the reason behind those atrocities” makes zero sense and is comparing functionally the same thing.
