If liberal means acknowledging truths, then liberal is better to be in some circumstances.
Trying to baptize a secular entity into the Lord never did work. Influence can be exerted upon it, but only people’s own choice can make them Christian or not.

Liberal does not mean acknowledging truths.

It is reflective of liberal logic and ignorance.
Whether the National Cathedral should or should not hold a Muslim service has nothing to do with whether or not the US is a “Christian nation”.
