If you voted him in as president and voted for a second term, you accept him. If you have denied/rationalized/diminished the many things he's done and said and not done and said, then you accept him. So the list of things that Trumpers accept about Trump is all inclusive. Under the circumstances of how historically and morally and functionally bad his time in office has been, and they still would have him as president, well that is the highest form of acceptance.
