Stripping a deceased person of their dignity via caricature is really a new low. This truly beggars belief and makes me very very sad. I hope the family finds peace.
But describing it as "a new low" against the background of a violent disruption of Congress, with the intent of interfering with the peaceful transition of power... that's not a phrase I'd have thought to use. The mockery is disgusting and disappointing, as is the gullibility of its spread, but both are very common. The violence, by contrast, is genuinely novel.
The violence is not ‘genuinely novel’. We certainly saw many instances of creative ways of violent destruction in protests by the other side in 2020.
Anyways...my 2c. Ymmv.
However, his social media posts before traveling to DC were enough to strip him of any dignity he may have had.
Its a low, but I don’t think its actually new, and not very uncommon in situations where there are both strongly divisive emotions and people dying.
