In fact, the woke criticism of it now is likely intended to shame blacks and young impressionable kids in general, for enjoying the fireworks and parades and being openly and unashamedly patriotic, so that in the future they won’t come out of the prisons of fear the left is holding them in, and mingle with their fellow citizens. Thus the left can take a truly diverse, universally enjoyed celebration, and turn it back into a racial thing, killing it off.
The leftwingnuts would rather have a week of mourning and citywide self flagellation, a giant communist “struggle session,” than a week of toleration and celebration.
