My grandfather was born during the Emergency years in the 1940s and grew up in the 1950s when Ireland was destitute. All his hard life, he had to struggle for what little he had. However, he would happily go without so that his family was provided for. He is well-liked in the community and always has good humoured stories to share to brighten your day.
But he doesn't like the blacks. He mentions facts he sees on the news such as
fewer than half of the Africans in Ireland actually work. I suppose he's bitter that he had to work so hard his whole life for what little he has while more than half Africans step off the plane and enjoy a life of leisure living off the Irish taxpayer.
How can I change his worldview or is it too late?
