Oscar quotas?

[FuzzyPlum]

Quotas are certainly not the answer but it does seem likely there's institutional racism involved somewhere along the lines.
No black actors out of the 40 nominations for the top acting awards over the past two years?
either;
a) there's less of an inclination amongst the mainly white voters to vote for black people.
or
b) there's less opportunity for black actors to fill top roles.

oh, I forgot...
or
c) black (and other ethnically diverse) people just can't act.
