Can you help me understand the Conservative frustration with the Christian message at the Inauguration's Prayer Service?

From my perspective of Christianity, which ended after 10 years of Catholic school; she overstepped her boundaries by pleading our new leadership to remember a less modern version of Jesus. One that has empathy for the downtrodden, withholds judgement and anger, preaches love, was born while Mary and Joseph were escaping political and religious persecution as refugees, eschewed wealth and generally pitied those who did not (constantly, and I mean this was a big thing, reminding people that wealth is not next to godliness and quite the opposite), and always spoke truth to power. I understand that bringing up the teachings of Jesus can be antithetical to the week's celebrations by extremely wealthy and powerful men, but those men do call themselves Christian. I just want your thoughts on where his anger is coming from, was it just a slap in the face? Would it have been a slap in the face if you truly are Christian? Overall, I consider it a preacher (priest, bishop, whichever religious leader) to guide their community where they see them starting to morally stray.
