If it is important to each individual to declare their availability, or not, familial status, or not, then there are a couple places off the top of my head to do so. There is the Signature tag so it's displayed with every post so everyone can see it right away and the Biography section of one's profile page so one could look it up if they're so inclined. There's also legal ramifications that some people can't afford. In some locales (depending on region, country, state, etc.), to have any label associated with them at all even mentioning the woman as a wife automatically makes her a legal, common-law wife which makes the man guilty of bigotry bigamy which is a felony. There's also the issue that, again, to some, the very terms Husband and Wife is to accept the dogma brought on by a "Church" or "State" government that they abhore. And that by the way, is a classic example of how a typical modern feminist twists things around to have a misogynistic undertone that never existed. Being married doesn't make you NOT Male or Female. In that case, please also include your REAL name, address and age. That way we really know who we're talking to and can use the appropriate pre-determined bias. I realize this seems like it comes pretty hard but I think your whole post is making something bigger than what it really is. There was a simple purpose for having the Male/Female tags to begin with, so to make it more than that is a solution looking for a problem and is divisive. Don't be that person. EDIT: I spent too much time in edit. I see that it's been addressed. EDIT 2 9/24/17: Bigamy, not bigotry.
