Political tags - such as royalist, communist, democrat, populist, fascist, liberal, conservative, and so forth - are never basic criteria. The human race divides politically into those who want people to be controlled and those who have no such desire.

Liberal Christianity, of course, has enemies, but they are everyone's enemies - sexism, racism, homophobia. But liberal versions of Christianity, which can be both theologically and politically conservative, assume that what it means to be Christian qua Christian is to have no enemies peculiar to being Christian.
