Method to Discredit Liberals During Discussion.

Liberals live in a world of self proclamation and as such all that is need is to ask them to define concept(s) being applied.

Think about this for a minute. If you use a concept to describe self or other and cannot define that concept, does one even know who self or other is?

This tactic will lead to an endless deduction loop and is often expressed in a tautological form.
