In addition to getting the stigma from other divers I get it from non-divers, such as my family, asking why I don't have a buddy.
"What do you mean you going diving alone at night?! What if there is a problem?"
I had to work through that with my wife. She was initially quite reticent to me solo diving. She came around over time as I helped her understand the precautions that I take. I've also had a supposedly trained, qualified buddy run out of air on me on two occasions and on one of those he dragged me to the surface from 100' even though he was on my long-hose and had plenty of air. Those two instanced helped her realize that I'm safer solo. I have very few buddies I will dive with anymore. It gets back to @rhwestfall point. I know I'm always there for me.
In terms of anyone else, I don't give a flip what they think. It just shows their lack of experience and understanding as they are typically just parroting what PADI taught them in OWD. If anyone asks me what I do if there's a problem I reply that "I deal with it."
