I believe he would be shunned by the masses and accepted by the few. No different than he was in his time. Then after he was killed, blacks would act like they were down with what he was saying and post Malcolm X memes on their social media.
Not much has changed in the general psyche of the black population.

He would be welcomed with open arms by most, because despite all the c00ning we see on tv there are a lot of us who believe in what Malcolm preached.
