I do not think Kanye West is trying to attract attention with actions that has become controversial. Right from early 2000's Kanye has always spoken about how blacks are treated in America though his views on alot issues have been rebuked by many, Kanye has not stopped advocating for true freedom and equal treatment for blacks.
Even in his latest tweets, Kanye address how the 13th amendment is affecting those in prisons and a need for a change of the amendment.
I think Kanye has the interest of the blacks and he is not doing all of these to attract attention to himself.
