Find me one instance of a republican promoting hatred of the poor and I might agree with you. I doubt you can; the closest you'll get is republicans claiming it is not the job of the citizenry to support the lazy. Constantly pointing out racial injustice is not making it better, it is turning the country into a cesspool of hatred. If you can't see that just by how the atmosphere is now vs. 10 years ago, I can't help you. In terms of race relations, the 90s and 2000s were SIGNIFICANTLY more peaceful and less hateful. I have never seen conservatives divide the nation into rich vs. poor other than when speaking of tax brackets etc, which is unavoidable.
Christian vs. Muslim vs. Non-believer is again, coming from fringe conservatives without widespread support. Liberal/progressive vs. conservative I already acknowledged, though I again point out that for the most part it is not republican senators trying to push that hate, but talk show hosts, etc. Listen to Pelosi or Waters speak for more than 5 minutes and see the difference.
