please dont talk on matters on which you do not have sufficient information, like this assumption of yours regarding 'legal' nonviolent methods of mlk.
Thats your assumption not his. The person you are quoting and then trying desperately to prove incorrect explicitly said:
Like the non-violent methods of MLK, who broke the law in a way that brought attention and public opinion over to their side.
You claim to know a lot about history (or at least that GP doesn't know a lot about history). Perhaps you should read about Thoreau. He advocates the style of disobedience that the GP is advocating. Gandhi and MLK subscribe to this way of thought as well.
