In my opinion the "problem" with black people is a combination of many factors, some their fault and some not....
Slavery and racism left their ancestors ignorant and poor.
Ignorance and poverty breeds crime and crime leads to prison.
As a result they often come from homes with uneducated, poor, drug addicted or absent parents.
When you have zero guidance it's very difficult to learn right from wrong and how to succeed in life.
They are getting bad advice from so-called black leaders who do no nothing but make excuses for them and keep them hating white people.
As a result they think that anyone who criticizes or disagrees with them is a racist so they don't make much effort to change themselves.
Anger, resentment, hatred and hopelessness is poisonous to a person's soul. Eventually it causes you to stop caring.
When you "don't give a fuck" and you have nothing to lose then why not use or sell drugs, why not rob or assault someone? Why not?
White people then see blacks committing a disproportionate amount of crime and so they fear and distrust blacks.
When you have two groups of people (blacks and whites) that fear and distrust each other trying to live in the same country...you get America in 2016.
Good luck everybody!
