Sure the black lives matter is easily dismissed, lemme show ya!
There are five states of matter. Liquid, gas, solid, plasma and....Black Lives! Best start rewriting the all those physics books.
Of course black lives matter, but then again, I'm a guy who makes his living selling grape soda.
Like any movement it gets co-opted and commercialized, see-

Every movement can and is made fun of and mocked as well. Black lives matter being no exception.

Then you've got the politicians who don't give a shit about BLM except how they can use the BLM movement to further their own agendas.

Then there is just the name itself and it's racist connotations. How would you react to a "White Lives Matter" movement? There are those, they just don't call themselves "white lives matter" but it's the same idea.

It's all fucking racist. And nobody cares.
Did you know that more Colin Kaepernick jerseys have sold in the last two weeks than the entire previous eight months combined? People making lots of money on this and I'll give you a hint, it ain't Black lives matter making the money.
BLM is funded by Soros, that piece of shit fucktard who makes it a habit of profiting greatly on chaos. He burned the BoE for a tidy sum and broke a western nation's bank.
But whatever man, keep drinking the koolaid if it makes you feel superior. Whatever it takes to feel good about yourself I say, no matter how delusional you may be. Hell, the most delusional are probably the most happy, and the Black lives movement is delusional at best.
