An apology is only issued when one doesn't believe in themself, and as thus is a contradiction of character. Someone who constantly apologizes is a complete fraud as they apologize for all they do (or something another does, meaning they believe themselves inferior to that person and are consistently apologizing for what they believe to be institutionalized wrongdoing by their superior) and therefore stand for nothing.

The old saing "talk is cheap" comes to mind in this instance.
