President Wrong Metaphor

So our "literary" president thinks racism occasionally "percolates up", does he? It's down there in the murk, you see, sometimes rising (accompanied by the Jaws theme, no doubt) to break the placid surface. But, how does the mass dissemenation of a private, illegally recorded conversation constitute percolation? Isn't more like an aggressive drilling down to find "racism"? And why is there, apparently, no faction out there in favor of privacy? Why is there no respectability allotted the argument that one's private life should remain private, even when dealing with the tender sensibilities of black Americans and liberals?
