s2horn, I am certainly not offended, and I'll reply to whatever posts I want thank you.
Sorry that you took my post the wrong way and that you obviously got offended.
Like I said, contrary to what diagrams you might have seen, a switch box most certainly does NOT have to have two cables.
How do know it is not a switch loop? As Locknut stated, it is impossible to know your situation considering the amount of detail you are providing.
If there is only one cable in the switch box it is very likely that it is a switch loop and the white is NOT a neutral.
You don't have to reply to me, but why not tell the others what wires are in the fixture box and how they are connected.
