A comment was made about a lawyer making an argument which, in my opinion, is a bad argument. I pointed that out. I'm not being "pedantic" nor am I "nitpicking" when I point out that a potato cannon is, in fact, a deadly weapon and the lawyer's argument against it is stupid.

Now, I agree that the comment, and therefore the whole thread that followed it, was not really on-topic. But I'm not seeing this whole "pedantic and nitpicky" thing.
