They are offended by their inferences, not his words or implications. It is because they are the ones that are racist. The article said he was addressing about 20 DEMOCRATS. So he was saying he was raised similar to the democrats in the room.
Now, if he had done a Ross Perot and said “you people” that might have been different. He was talking to a group of politicians and said they have similar pasts. And that is relative. I am assuming none of them were raised in Sudan.
What a bunch of whiners.
If I were Scott I would have retorted; “There’s not a whole lot I can do about individuals who harbor feelings of insecurity and resentment. They have to figure it all out on their own.”
