May I suggest that you alter or drop the "who cares" part? That kind of dismissive rhetorical question will make anyone listening more willing to dismiss what follows out-of-hand as well. I very much agree with the core idea of what you said, but I felt my hackles rise as soon as I read the first sentence and I imagine anyone who actually disagrees won't even bother considering your side after seeing that you seem to not even care to consider their side.
