I struggle with that too. I know lots of people where we live and of course they all know I'm married. To boot where we live is kind of the Bible Belt of Alaska. So there is a lot of condemnation for anything "different".
So far we haven't really come out in public, and we're pretty careful. But I worry more for my husband's work associates than the public in general. For myself I don't care what other people think-I only care what they think/do to Maca or C. Because of that I leave it to them to decide how much we come out to anyone outside of "our circle". But my friends and loved ones know I'm poly and most know that there is more to our situation then we've ever said. They don't care.
