I certainly can't speak authoritatively for the opinion of anyone other than myself, but it seems to me that everyone can easily be convinced to agree that if something is, then it is; and also that nothing can both be and not be at the same time and in the same way. In other words, the Laws of Logic are valid.
An interesting point to note, however, is that the Laws of Logic can only be valid if Christianity is true.
Atheism must either acknowledge that infinity is not infinite, or that nothing is not nothing, making the Laws of Logic invalid under Atheism.
Polytheism insists that things that are may not be, making the Laws of Logic invalid under polytheism.
Any Monotheistic worldview without a divine atoning sacrifice insists that debts can actually be paid by one who has nothing to pay debts with, again making the Laws of Logic invalid.
Christianity alone stands coherent, allowing for the possibility of knowledge via the validity of the Laws of Logic.
Why Christianity?
Certainly. I'll bet we all agree spring grass is usually green and a clear sky usually blue, objects fall to the earth at approximately 32 feet per second per second, and Audrey Tautou is beautiful. Just for starters.
