Oh heaven's above, you're ridiculous! It's a point of grammar, not comprehension. I understood the sentence, and most probably would, but it's still a clumsy contraction. Not the end of the world, we all do it, but a bit of a faux pas when you're making a point about grammar. "Degrading" isn't a particularly good word to use in that context either, but you weren't being prissy about semantics.
