Ahh, you want to kill some content, aye? Lets see, which hatchet will work best - can't immediately find flaws in the logic, so that one's out; same deal with the math. Let's look broader - let's just say, ah, this content may be sensible, useful, it may even be accurate, but we'll just accuse it of poor tone - specifically we'll kinda gesture at workplace norms and say that it's unemployable (why not add in a bit of implied ad hominem to spice things up?) That'll do the trick~
