It’s not just “term usage”.
It is weaponzing mainstream language to neutralize any activism towards obtaining equal rights for marginalized groups.
It is subtle and extremely potent.
Convince the average American that Black Lives Matter is just a form of “Identity Politics”, then you devalue an entire movement in the mind of that Average American.
You, in effect, garner the public opinion and support necessary the justify the systemized slaughter of unarmed, innocent specific types of people by the very law enforcement agencies constitutionally obligated to protect them... all with the simple “usage” of a “term”.
