What are some examples of previously-hated minorities that are now widely accepted?

I've been doing a bunch of reading about different immigrant waves to the US in the early 20th century and it's shocking to me how extreme the backlash against them was.<br><br>Italians were seen to be crude and unintelligent. The same was said of Polish immigrants. Irish immigrants were seen as alcoholics and union organizers. There was a lot of backlash against all these groups, especially Italians and Irish. They suffered a lot of religious and ethnic violence.<br><br>Now, I don't think anyone is actually racist against these groups. I can't even think of a stereotype for any of them. They're just seen as white people.<br><br>What other examples exist like this, globally and throughout history? Or can people's minds only change so much?
