I agree with him to an extent
Its
not our expressiveness that's an issue, its when we do it at the
behest of white people for entertainment/acceptance that is a problem.
As if we cannot communicate without some sing-song dance bullshyt.
Look at Hillary Clinton
I'm Nigerian, we dance all the time.
-Church
-Wakes
-Funerals
Basically times when everyone else would be solemn or serious.
And we make no apologies for it. So he can FOH with telling Africans not to dance
But let a white man come up to me and say "Show me how to shoki

"
And that goes for everyone whippin and nae-nae'ing for these cacs too
TL;DR: Be expressive if you want, have fun if you want, but be mindful of the company you keep and if you are being used or not.
