The term “Black Lives Matter” and “BLM” are more than words, they are an ideology if you will. Using them in any way only serves to further their agenda.
Calling them out as haters and Marxists and anti-justice monsters and useful idiots etc is necessary. Avoiding their terms is in my opinion essential to deflating the perceived value or gravitas they desire and possess to some degree already. They are an insidious virus as dangerous as any biological agent. Inoculate and protect is needed. They need carriers to spread the disease of hatred and counter-racism and it seems silly white women and snowflake boys are most susceptible. The “gibmedats” are still gang banging and dealing drugs among themselves, happily and liberal cities and states are purified to do anything but acquiesce up til now.
They all will reap the whirlwind, eventually.
Forcing them to either support all "Black Lives" or distance themselves from our message would indeed have an impact, especially among those who are disgusted with the movement, but fell the need to support its main message.
