You realize that your post actually illustrates the very point they are making here! It's the ridiculous, oversensitive feigned outrage over silly, exaggerated or fabricated reasons that they are pointing out. Some comedians won't even do colleges anymore, because so many students have been "conditioned" to be offended by everything. There is REAL suffering and oppression going on in the world, but in the mean time we have spoiled, privileged Americans who are conditioned to expect to be fawned over and treated as victims, because of something stupid, like they took something the wrong way, or couldn't handle a harmless joke! To people like that, I'd say to remember that it's NOT all about YOU. Think about what it's like for people who are starving or dying of a tropical disease somewhere else. You have it much better than they do! Quit with the personal pity parties...
Nobody is "diminishing" anything. They are making the point that MLK was trying to solve legitimate oppression, while most modern SJW's are usually just screwing things up, being selfish, or trying to push a separate political agenda that isn't even really related to their SJW agenda.
