....why whenever a Black organization rises to fight for equality, it is deemed as a "terrorist" , "radical" or "militant" group when there are groups such as the Klu Klux Klan and other White Supremacy groups and their descendants can openly kill and spread hatred towards another group of people without penalties.
You are starting with a premise and expecting other posters to fill it in for you; in other words, you have reached a conclusion and made some claims in a general sort of way, state all black people never get a fair shake and state the KKK is still killing people via their descendants and provide no proof of any sort to illustrate you are educated in the current state of affairs in the US.
First of all, BLM actually is a communist/terrorist organization which they have laid out squarely on their site. Look it up and read it for yourself and then come back here and try to explain why you do not think that is so. The KKK were a Democratic organization and not Republican.
As far as openly killing black people in the US goes, there is no race that is better at killing itself than the blacks in the US are.
Every Democratic run city has massive problems with shootings, rapes and murder and innocent people, including actual babies, being killed by bullets meant for someone else. Please advise us how you are going to take care of that problem and please provide statistics or some sort of proof of this murder you feel is being committed by whites against blacks
