I think you guys may be using different definitions of what it means to act like a christian. If you disagree on that then you’ll just keep arguing past each other.

When you refer to acting like a christian that seems to mean acting christ-like, or at least striving to, which makes sense.

The other usage I’m seeing, and which is probably more prevalent in societal/political discussions, is that being like a christian means being lily the actual group of humans who use that label, which often has nothing to do with christ-likedness other than in name.
