The Black Power movement led by Malcom X had ideas similar to King's movement, being that they both wanted rights for African-Americans, but the way they protested is where they differed. Malcom X criticized MLK's method of peaceful protest, and took to having a more radical and violent way of protest and fighting back against oppression. I hope this helps :)
I agree, because most of them are in the wrong crowds. This effects the younger generations drastically; therefore, each generations after will be influenced.
