I was involved in the Yes campaign and I had a fun example of this. A woman who was originally from Ireland a few decades ago and had overstayed her visa would not support it because SHE couldn't get a driver's license when she had been undocumented. She shrugged off the argument that the new legislation would mean that others in similar situations wouldn't have to go through the same trouble she had. And then she shouted some weird threats at us as she drove away.
