My husband and his crazy uncle were just arguing about this after the AZ shooting. Ray is positive that Oswald was set up by his right-wing handlers and no amount of facts will change that in Ray’s mind.
I don’t bother with any discussions with Ray & I keep reminding my husband about the saying “Never try to teach a pig to sing, it wastes your time & annoys the pig”, but my husband still tries to bring a bit of common sense into his uncle’s life.
