I’m sorry, but these questions aren’t really what this thread is about.
You have zeroed in on the most frightening aspect of Obama’s pronouncement. What, exactly, does it mean? Does it mean that whoever owns the land now (one hundred-plus years later) is going to be forced to give it up to “the descendants of former slaves” — who likely never owned the land in the first place?
And, significantly, what does this portend for the US if Obama is reelected? He has now said he favors taking land from its current owners to “return” it to the “descendants of former slaves.” If — no, make that when — applied in the US, it will mean that the government will dictate what land it decides should belong to “the descendants of former slaves.”
And then, the tyrannical confiscation and redistribution of land will begin with ruthless ardor.
