Here's the thing about the word 'hen' here in Swe that you don't hear if you aren't "within the borders" (Swe is brilliant at creating an awesome international image of itself, but that's bending the truth.)
Outside Stockholm and its protected "little sphere", it's generally laughed and scoffed at. Personally, I see it as an easy word to write instead of "him or her" (so I don't dislike it as such), but its actual purpose remains useless.
It's a simple way for politicians, strawfeminists and other "Politically Correct" people (who are oversaturated in Sweden to begin with) to gain kudos points. The bottomline is that adding a word does absolutely nothing. It's an empty gesture. It contributes nothing, other than turning people on the fence against feminism/equality even further because they find it silly and destructive. People have been called misogynistic and anti-feminist because they don't like the word, which is a common modus operandi with everything here in Swe.
IMO, equality comes from high political levels and through a dialogue with the people, not through adding silly words. Through action, not empty PC talk. Calling a boy "hen" in the belief that calling him "he" triggers negative masculine traits simply serves to create resistance to the whole hijacked movement. (There's a debate storming regarding all this, but most of it is in Swedish.)
And, yea, expecting only positive reinforcement in a forum thread is hilarious.
