Self defeating arguements

A self-defeating argument or idea are propositional statements whose falsehood is a logical consequence of the act or situation of holding them to be true.

Sometimes the best way to argue against a world view, like moral relativism or unbridled skepticism, is to simply show how the proponents’ propositional truth claims defeat themselves. Like the statement “there is no objective truth” when uttered by a post modernist is logically self defeating and should be exposed for what it is. Sloppy thinking.
