It would’ve been inflammatory and radical (i.e., actually threatening to the status quo) if he’d mentioned specific means to addressing grievances, which he didn’t do in that speech. Rather, in that speech, he cautions blacks not to use violence, and otherwise stays vague and non-threatening:

Go back to Mississippi, go back to Alabama, go back to South Carolina, go back to Georgia, go back to Louisiana, go back to the slums and ghettos of our northern cities, knowing that somehow this situation can and will be changed.

That’s it. Five years later, however, King was talking about not only the specifics of how capitalism allowed racism to persist, and but also the nature of U.S. hegemony in the developing world. That’s what made him truly radical, and that’s what our collective depiction of King wants to erase. Now, all our children hear about King is “I have a dream.”
