For better or worse, the word "cynic" has changed meaning over time. My usage matches definition #1 here:

That matters not to Cynics and is only proof of the very corruption we mock.

There's something ironic about a cynic, in the classic sense of "question everything and undermine assertions", protesting the corruption of his own self-declared title. ;-)

The Ironics are a different school of thought.
