Hypocrisy: The practice of professing beliefs, feelings, or virtues that one does not hold or possess
Having no values or beliefs and being self-consistent with ulterior personal values does not change the definition of the word.
If one professes beliefs, feelings, or values that one does not possess, one is a hypocrite.
Yes.
Profess: 1) To affirm openly; declare or claim. 2) To make a pretense of; pretend.
If one makes a pretense of holding beliefs, feelings, or values that one does not hold, one is a hypocrite.
Whether anyone else understands the pretenses of the hypocrite or not does not change the definitions of the words.
