Your comment is nonsensical.  And political correctness aside there are some things that are simply correct.
If you can't divide 15 by 5 is the problem that Math is racist or could the problem lie with government run education systems.  Is it a lie that 15 divided by 5 is 3 or is it that it was discovered and documented by white people to equal 3 and there is actually a better black or brown answer? 
The politically correct truth is that the left doesn't believe minorities are capable of learning math and that is the soft bigotry of low expectations. 
I repeat the real bigots in the issue are the public schools, their unions and the idiots like Gutierrez who make excuses for them by blaming everything on institutional white racism.
