If those men are transplants, isn’t the demographic skew partially their fault?

Yes, if you move to an area that's known to have dating demographics badly skewed against you, don't be surprised when your dating life there is disappointing.

However, when we have a discussion about Bay Area dating, and most comments blame men for "not being interesting" and completely ignore, deny, or fail to even mention the gender imbalance, I don't think it helps men to make informed choices.

The fact is that either because of infanticide or nature there are fewer younger men in the world so you’ll have this problem in most places.

> fewer younger men

I'd expect fewer young women?

Yes that’s what I meant to say.
