By almost any recognizing current society (and this is in real stuff, not TVLand depictions) is (at least on a social level) much better than it was even in the recent past. We have more resources, we have more people who are - I hesitate to use the 'educated' word - 'aware' of mental illness, phobias and other mental issues, and there is far more sympathy/empathy (a little of both I think) toward people who suffer with those things than there ever was. Yet - and this is interesting, most interesting - the more we know, the more we're open to it as a society, the more therapy there is, the more therapists that there are, the more people who have problems that there seems to be.
You'd think at some point the numbers would begin to turn around, but they never do. Matter of fact, the further we go, the more we turn up.
So the reasons/causes (and I'm not sure at all which it it, and it does makes a huge difference) probably do not reside in how open/accepting a society is. Matter of fact I'll bet you (though the reasons/causes may not actually relate) that the places that are the most open and accepting have the highest levels of therapies and the highest number of therapists.
Places like this wouldn't even exist because there would be no need.
While you would no doubt get fewer 'I'm going to kill myself' posts, and perhaps fewer of the extremely far-out ones that crop up from time to time I'm reminded that 'like attracts like' and all sorts of strange, odd and peculiar narrow-interest/common purpose/common ground type things have web pages/publications/shows/conventions all the time.
It might be more of a calender/sharing-board/social deal (with an extensive 'how do I get started?' section), but it would be here in some form. Like attracts like, and certain specific sub-interests have unique questions/problems that only that sub-group is capable of solving.
