If society stops whining about race and stops inculcating racial animosity and hate things could improve in 15 or 20 years.
Children are bombarded with ideas that divide us along racial lines from the time they are toddlers.
Stop teaching kids from the day they can talk that whites are evil people of privilege whose top priority is to kill blacks, take things away from them and make them suffer.
Stop teaching them that everything bad that happens to blacks is caused by evil whites.
Stop teaching them that blacks need the government to take care of them, protect them and give them special privleges because they are too feeble minded and incompetent to cope in the world on their own.
Stop treating blacks like farm animals who are penned up, fed, and fattened until they are needed on election day.
