At no point have we actually established that women are less likely to play strategy games (or games in general - a claim also made in the thread that unlike the strategy game assertion isn't supported by the evidence) - we only have the evidence that 98 per cent of the viewers of Adonnus' vid were male. This is far, far too small a sample, not to mention far from a balanced, randomised sample, to draw any conclusions.
And then we have the many normative assertions about "women's" behaviour, many of which were incredibly and patronising and misguided (I'm not picking out examples here as to not specifically aggravate anyone). Women, like men, have a huge range of interests, motivations and hobbies.
Starting with games more broadly (which some in this thread have asserted women aren't as interested in as men), multiple studies have shown women making up a larger proportion of all gamers than men, and even the studies that don't have them in the majority, have them very close to 50 per cent. The assertion that women are significantly less likely to play games than men is not borne out in the available data. Rather, it is an assertion based on individual experience. As many have noted, this is often misleading, as many women prefer not to disclose their gender when gaming online because of the way they get treated if the do.

As for strategy games, the research I could find supports the argument that it is the case that women, more broadly, are drawn to different genres than men (although there are overlaps), and that strategy is one of the genres that tends to be less appealing to women, but this doesn't mean that there are no women playing it. I've just done some quick googling, but based on iOS gaming, around 20 per cent of strategy gamers on iOS are female (
http://blog.apptopia.com/game-demographics-that-every-developer-should-know/). I know iOS strategy games are a pale shadow of the stuff we all play, but there's a reasonable chance it's broadly indicative. Another study pointing towards a male bias in strategy game audiences is
http://psychology.wichita.edu/surl/usabilitynews/141/videogames.asp (noting that it found that 47 per cent of females played violent games, so while it was less than males, it's hardly a negligible proportion).
In answer to the OP, the Wichita University study is probably the best read, but none of the stuff I could find categorically explains why women are less likely to play strategy games - but things like 'guilt while playing' would mean a tendency towards games with shorter durations, as would a tendency to prefer playing on console or handheld, where strategy gaming (as we understand it - I'm not talking CCGs or Pokemon-style games) is less prominent. I'd expect that differences in socialisation and possibly biology may give mean women are more likely to have interests in other areas ahead of strategy games. That said, I'd still expect that there's a decent proportion of women playing PDS titles, but that like in other genres, they generally keep their heads down and gender to themselves because of the nature of the internet.
Another thing to keep in mind is that most strategy gamers play single player, and most never come to the forums, so individual responses to a forum thread on the issue are unlikely to be representative.
