> I would suggest looking more into what he was actually about, rather than taking at face value a few words from his most popular speech.
I've listened to that speech over and over again throughout the years. I think he was utterly sincere in his desire for equality and brotherhood between people of different racial backgrounds. Most of the time, the simplest and most straightforward reading of a text (keeping the context in mind - author, audience, circumstance) is also the most correct. I believe he was not being duplicitous.
> your grade school understanding of MLK is not helping things
If you're referring to taking things at face value, then I proudly stand with grade schools insofar as they teach children to take people at their word and take truth at face value. And I defy the university-level critical (or rather, cynical) theory that seeks to redefine all texts according to its rubrik of oppressor/oppressed.
