I won't bother with the rest, but you exhibit a lack of understanding of the difference between "wouldn't" and "shouldn't". My use of oth was correct and appropriate, and the way that I used them gave emphasis to the difference between the two words. It may be a slightly non-standard use, but it is certainly not an error, and it most certainly was not sloppy, because I intended to use the words that way. By the way, "should" and "would" are not auxiliary verbs. "Should" usually is a conditional, and "would" is a form of "will" that is used in several different ways.
