I've watched a few of the reality type shows where they go into an adult bookstore with an obvious video camera and start taping the people inside. They scatter, pull their coats over their heads, turn away, and run. Within seconds the store is empty.
I've often wondered what the scene would be like if this happened in a gaming store. Would there be people who reacted the same way? It's possible, but I doubt it. That alone tells me that the stigma from gaming is not nearly as bad as you might think.
