Yes definitely, its been ongoing for decades, but I mark the most recent offensive with the Treyvon Martin event of 2012, which was highly astroturfed and supported by an intentional campaign of false information by big media corps. Since then it has been on repeat with every dead negro they could muster until they went nuclear with george floyd. Parrellel to all of this has been the ongoing effort to shift the rules on racial language toward overt hostility toward whites, which really didnt ramp up until a few years later.
