Right. Because if they believe in not killing or stealing, loving their neighbor, helping people who are different from them rather than judging, and so on, that’s Christianity.
And if they believe that people should look after themselves, try to be rich, and that America should stop letting in all these non-white people, that’s somehow Christianity too.
By now Christianity has expanded to cover a tremendous range of beliefs, practices, and values. The one they all still keep is the centrality of God and his son Jesus. Take that out and I’m not sure the word means anything. Ayn Rand and Karl Marx are both famously atheist, from Christian traditions, and disagree on pretty much everything that matters.
