This attitude is not uncommon among tech divers. That’s where the nasty attitude I’ve encountered comes from. I’ve been called lazy, incompetent, and an unsafe diver because I needed assistance with gear or in/out of the water (primarily boat dives) due to my knee issues. I’m full cave, solo, and now CCR (mod 1). You don’t get to that point if you’re an unsafe diver.That qualifies for being a jerk (or something more rudely descriptive).
ETA: can’t forget that some people actually accused me of faking the knee issues.
