Well let's step back for a moment and use some deductive logic shall we?
1) This current movement is based on a perceived hate crime. A white man shooting black people. Ok. Pretty simple really. As a reaction to this, there is now a movement to purge symbols of perceived hatred from society. Again. Pretty simple concept.
2) So in keeping with this thought process, I move that all traces of Martin Luther King be expunged from American society as we know it. Buildings need to be renamed, and statues need to come down.
How can I even for a moment think that anything Doctor King ever did is even remotely similar to what Dylan Roof did? Pretty simple actually.
In the mid 1950's, having been threatened on numerous occasions, Doctor King applies for a weapons permit to protect his home and family. His application was actually denied. He then stocked his home with firearms provided by family and friends. His intent in having these weapons would have been to shoot people, specifically WHITE people, that he perceived to be a threat to him,his family, and way of life. You know, kinda like how Dylan Roof is said to have seen African Americans.
Only through pure luck, there is never an attack on the King home which requires Doctor King to commit a racially charged homicide using the weapons he at the time kept illegally in his home. To his credit, he later removes the weapons, as he sees they are not consistent with his non-violent approach to dealing with the issues of racial strife in America.
So, forgetting his contributions to mankind, and approaching this from a PURELY logical and legal point of view, MLK kept weapons illegally in his home, and was prepared to kill the white people that he perceived as a threat. Dylan Roof had a LEGAL weapon and killed people HE perceived as a threat. You can definitely argue that one was a nutbag, and the other merely engaging in legitimate self defense. I will strongly suggest to you however that there are people out there who think MLK was the nutbag. THAT is the actual problem you face as a society.
the flaw in the logic was actual threat and protecting ones home
king did not only receive threats from whites,, and there is no evidence he was going to go SEEK out white people to kill
Im sure, ANY threat, black or white that would follow through with attacking his home, would be met with the same DEFENSE
the incident at the church was not a defense, it was an offense
