I didn't say I had a problem with you. As far as I knew, you asked about the dialect/use of a word. I don't think it's an issue to really debate. We call it the sweeping fist. It makes sense to me.
If you want to call it something else, that's okay too.
Sweeping fist, sweeping kick, same character to me, same motion. Yes, the fist technique can come from different angles and use different hand positions. It's still the same motion as the sweeping kick, regardless of what plane it's on.
That is how I see is. The character debate is really out of my league, as I can only read about 100+ characters.
Peace
