What side of the counter culture position would you have been while MLK was pushing for reform? Would your line "its clear which way the cultural winds are blowing today" align with the prejudice side? I think so. Do you look back and see that movement as an evolution and betterment for all of mankind or do you see it as "winds were blowing the wrong way"? Change is hard and change requires you to acknowledge your line of thinking, beliefs, ethics, all of it may be out dated or no longer the form. Imagine how folks born at the turn of 1900's felt when MLK was popular.
