Ah yes. Pardoning folks who were imprisoned for possession of marijuana is exactly the same--worse even, because "autopen"--as pardoning folks who were imprisoned for insurrection / political violence in support of the guy doing the pardoning. Very smart take.
18 were charged with seditious conspiracy. Over 500 were charged with assaulting, resisting, or impeding law enforcement officers. And many more were still awaiting trial, including Daniel Ball, who was accused of throwing explosives at police officers, were also pardoned by Trump. Many of these pardoned individuals have gone on to commit further felonies, including Daniel Ball, who was just arrested for plotting to murder Hakeem Jeffries.
But again, you seem to be missing the point: a president pardoning people who support him is very different than pardoning ordinary people who were imprisoned for crimes that are no longer crimes.
Biden issued several blanket pardons for any crimes that people may have committed for a period of a decade. That doesn't strike me as particularly discerning.
