rhyming and cannibalism in protest songs

So, I know it's cheating to rhyme a word with itself. That doesn't work. But what about rhyming a word with another word that is a derivative of the original word? The example I'm thinking of is in Barry McGuire's (well, P.F. Sloan's) "Eve of Destruction," in which there are a couple of lines in the third verse that go thus: "and marches alone can't bring integration, / when human respect is disintegratin'." Now, this example isn't an exact rhyme to begin with, the first word having the noun ending -tion and the second having the gerund ending -ing. It's just the way he sings it (leaving off the final 'g', for one thing) that makes it sound like a rhyme. But assuming one were to use this pair of words in a different context with the same ending—could one rhyme "integration" with "disintegration"? I feel like the answer would be no, but I honestly don't know.

On a completely different note, that bit near the end where he says, "Hate your next door neighbor / but don't forget to say grace,"—when I was little, I always heard "eat" instead of "hate." I didn't actually know it was "hate" until I looked up the lyrics online. Yeah, I was a weird kid. But I like my version better.
