Oh, my research into the matter was propaganda? Is all of the rest of the actual data propaganda too? You have anecdotal evidence, which I have no doubt your grandfather believed was true, but which does not necessarily mean it is correct. The fact is that the vast majority of those who fled the USSR citing persecution had very much done something worthy of persecution. Most commonly, withholding the means of production from their workers.
If I am wrong though, show me the proof. Anecdotal evidence is useful for verifying knowledge, and for creating hypotheses. For proof though, actual data is required.
