OK, so when someone tells me they are doing a basic recreational dive, do I have to ask them if they are going wreck diving, nitrox diving, drift diving, night diving, hunting, taking pictures, etc...? The phrase, technical diving, has a meaning that encompasses different types of advanced dives. There is a difference between recreational diving and technical diving, and that's why the phrases exist.
If I tell someone I do technical dives, most would automatically assume overhead or deco diving (ceiling diving). If someone tells me they are a recreational diver, I can assume they aren't dealing with significant ceilings. Having the two phrases is simply a matter of separating two distinct types of diving -- overhead/ceiling and OW. I would argee that technical diving includes many different dives, skills, and equipment requirements (as can recreational), but the underlying definition is the same -- a ceiling of some sort is involved. Sure the phrase covers broadly (like recreational diving), but it certainly has a distinct meaning/definition that is generally understood in the diving community (or at least I thought so).
I didn't realize the phrase was so offensive

PS. Just for the record, I consider all of my dives recreational -- just to confuse things a bit more.
