To be acurate, very little would change in the US in the way you would hope. The NSDAP had more than a few homosexuals even though it was not condoned. If you read Mein Kampf you would know that Hitler had no policies against blacks, but he did not recognize their status as citizens. They would not have met a fate similar to the jews but I doubt they would have enjoyed Europe much either. As for the jews, not too many more would have died, they were already rounded up for the most part and those who fled were safe. The state of Israel would still have been founded and become the same haven.
Something to think about, if Hitler had won, more people of the same groups you mentioned would have fled to the US and increased the population here. Then you would really be pissed.
