I’ve thought hard about this quandary. Is there a real analogy between being out poly and out gay? I don’t perceive a lot of hate-crime and familial repercussions against the poly community, so I hesitate to make the analogy.
That said… I’ve hesitated to tell the entirety of my social circle my situation. I have butted heads with several friends, and will continue to do so.
So, all in all, good on you!
