They have the one passion, that condemns every hobby to a sparse existence.
This passion is to seek group approval and climb the social hierarchy. While man have sex, to just enjoy it, women have sex, to climb the social ladder. It's their expression of their sexuality.(Beside banging chad in obscurity)
According to Paul Watzlawicks "You can not not communicate."
I say "Women can not not take part in fight for social hierarchy". Imagine it as desire, that can never be satiated.
As a men I really appreciate the fact, that my sexual desires can be satiated for a few days, which gives me the clear head for pursuing hobbies, intellectual adventures or business. Women can rarely enjoy that silence from their sexual desires, because their sexuality is in large part a means of manipulation. The manipulation games, which are driven, by their sexuality never stop for them.
tl;dr Women can not be satiated in their sexual desires, which express in herd mentality and climbing the social ladder. So they just never have a clear head for hobbies.
It seems like for some reason many of the past hobbies that women usually did have fallen out of favor because of facebook/instagram whoring.
Previously, many women had hobbies like knitting, crochet, baking, sewing, needlepoint, and scrapbooking. Because many of these are viewed as things "housewives" did, all these strong independent "womyn" can do what is really fulfilling to them: Instagram whoring and spending men's money.
