I have been very lucky and only ever had one ER doc be a douche about it. I've had people back away from me when they found out but if they will listen I educate if not screw 'em.
The only stigma that really fried my biscuits was a lady I worked with coming to me to talk about her BP husband. He had hit her and she said she wanted to talk to me about it because i would understand he couldn't help it.
