I have normally had natural separation by dive site, meaning that in most of the cases in which I have been diving, everyone else was a technical diver, too. Last year I did several local dives with people I met via ScubaBoard, and those were extremely positive interactions in which they asked a ton of questions about the gear I was using and why. In one case we talked about the advantages of wet suits v. dry suits, and he was pretty sure he liked diving wet. Of course, we had to cut our second dive severely short when he started shivering. That was the only faint glimmer of an us v. them tone.
This past February, I did a lot of typical recreational dives in Florida while FULLY rigged out because I was taking some classes and had to perform a lot of skills. Because these were skills associated with deep diving, I had to be rigged for it; because the skills could be done in shallow water, we were taking the path of least resistance and diving off of regular recreational trips. There was no hostility whatsoever from anyone else. There was some joking comments like, "Dudes, you do realize this is going to be a 60 foot drift dive, don't you?" Other than that, it was like we were just any other divers on the boat.
During that same trip, I went alone on such a trip so that I could simply practice my skills for those classes. I got grouped with 3 people who looked to be in their late 20s. I told them why I was there, and I said if they see me doing something without wagging my light at them as an emergency signal, they should ignore me. Even though I made that warning up front and repeated it before the second dive, they very alertly came up to me a couple of times on each dive to make sure things were all right when they saw me switch bottles, shoot a bag, or go through valve drills. It was nice to know they were paying attention. On the boat, they were very pleasant and respectfully inquisitive.
So, no, I haven't seen anything like it, frankly.
