i'm not sure how to explain this but i'll try. Don't know if it will make any sense...
i think one of the problems in finding accurate statistics is that there are so many people who are afraid to reach out or open up to someone. There are too many voiceless, unaccounted-for groups (or individuals) either because so many of us are afraid to speak up honestly or because we're in a grey area and the polls we're responding to & the articles we're reading are black & white.
Ok - sorry - losing where i was going with this. if i made any sense let me know.
