If you understood critical thinking at all you would know what you are asking for is impossible. What I'm trying to figure out is if you are too dumb to know that, too dumb to realize your gotcha is not one, or both.

Let's look at my statement "private schools have used uniform sales". The question ~~you~~ an intelligent person would ask is at what point does the number of schools that do not have used uniform sales invalidate that statement. Not even the biggest mouth breather would claim that only one school that does not offer a used uniform sale invalidates the statement, they would be adept enough to notice that the word all is missing.
