Why would the reptilians conspire against minorities and not all of mankind? I would assume they would find better ways to use their time than race
wars. What kind of motive could they have? It sounds a little far-fetched to me. How old was he when he told you this? Is it possible that he had
a mental disorder or was using drugs, legal or not? I mean, it's possible, but.....
Is your uncle still around? If so try to learn more. See if he knows of their motives, etc. What changed when they came in? Anything like that
Now if they disguised themselves as clowns, then we would be in trouble. Who doesn't love a clown?
