>I don't see how that's a meaningful distinction from people who have made the color beige their sole personality trait

I'm not really sure how to respond to that. It's intrinsically different. It's getting responses from people who don't care what their neighbour thinks about them vs getting responses from people who care in the utmost what their neighbour thinks of them. One is intrinsically likely to be more unfiltered than the other.

If you want to know what sentiment a community actually holds you have to seek out all types of opinions.
