Let's be perfectly clear about this. I am not pedantic. I'm precise.
True, I'm very careful to find exactly the right words to express every nuance of my thoughts. And it's important to make sure that I address every single point relevant to the topic at hand. Sure, maybe that requires using footnotes from time to time, but there's nothing pedantic about that. Footnotes are an easy way of making sure that you include everything without losing track of the main focus of your topic. They're a sign of organization, not pedantry.
And yes, as a matter of fact, it is important to address every little factual inaccuracy, even if the intended meaning is perfectly clear. Accuracy matters, after all. Plus, you never know when a particular distinction, however subtle or unimportant in its current context, might become an issue of vital importance in some other setting. So clearly it's best to correct these issues as early as possible.
I'm not pedantic; I'm precise. That's all there is to it, really.
 This didn't require a footnote.
 Okay, maybe not. I'd also like to remind you that I have opinions.
