Let me provide a play-by-play reaction to your post...
You obviously don't know what the phrase "begging the question" means
Crap, did I accidentally use it other than how I intended?
*goes back to check*
No, I used it exactly as I intended to. Is it possible I've been misusing it this entire time without knowing any better?
*pulls up a DuckDuckGo search in another window while reading the rest of your comment*
and aren't willing to find out
Well, that's a rude and baseless assertion that isn't supported by any evidence. I certainly wasn't willfully misusing it, and I'm not aware of having received correction from someone in the past. That said, I don't get notified when ACs respond to me, so it's certainly possible that you or someone else has been screaming at me about it for years without my awareness. I should still check whether I used it correctly, or maybe he'll tell me how I misused it if I just read a bit further.
so really the best thing for you to do is just stop using it instead of abusing it.
...seriously? Rather than provide a helpful bit of education or correction, you're simply telling me I'm wrong and should stop? Give me some credit. This is Slashdot. Many of us are open to receiving correction when we're wrong. Some of us even enjoy being told why we're wrong, simply because the quickest way to ensure we're right is to learn from our past mistakes.
For anyone curious: I abused the term. While the way I used it (i.e. to mean "inviting the question") is well understood in everyday usage, it's incorrect in much the same way that "I could care less" is almost always the opposite of what the speaker actually intended, yet will still be understood by most listeners. Particularly in legal and logical contexts, "begging the question" strictly refers to a form of circular reasoning. For instance, "reasonable people think and reason intelligently" begs the question "what does it mean to think and reason?", which leaves you right back where you started.
I really should have been aware of that already, but clearly I've incorporated the incorrect usage into my own speech. I'll try to do better going forward, so thank you, AC, for your correction, though it may have been mean spirited.
