Final answer:
There is a misunderstanding in the question regarding Craig Lockard, as only Craig M. Loftin is referenced with no mention of Lockard's philosophical arguments. Without correct information, it is not possible to identify or describe Lockard's argument.
Step-by-step explanation:
The question seems to be inquiring about the philosophical argument or claim made by a certain Craig Lockard. However, based on the information provided, there appears to be a confusion as Craig M. Loftin is mentioned instead, who is an author and teaches in the American Studies Department at California State University, Fullerton, and has written about gay and lesbian voices in Cold War America. We do not have information on a philosopher named Craig Lockard or their argument to identify or explain. Without the correct context or source, it is challenging to accurately identify and explain Craig Lockard's claim or argument. Philosophical arguments usually involve a set of premises leading to a conclusion, and the strength of the argument depends on the soundness of these premises and the logic connecting them.
