Women on my team often want to "gossip," but I've learned to recognize it for what it is: a (misguided) attempt to build rapport with me. I'm learning to redirect the conversation to be more positive. The men on my team are more likely to be jockeying for position, claiming credit for things they had small roles in, and generally exaggerating the truth. I'm learning to ask follow-up questions to get them to think twice before making any claims.
Males on my team are just as hard or harder to retain when compared to the women. I believe they're more likely to leave when they're passed over for a promotion or raise. Females at my company are perhaps more likely to leave because they aren't feeling close relationships. Keep in mind that the reason someone gives you for leaving is not always the real reason. The author doesn't seem particularly sensitive, so I wouldn't be surprised if she's getting "reasons" for quitting that are actually just evasions of hard topics.
These are all just my observations and experiences, but I'm sure there are plenty of studies showing the pros and cons of hiring men and women. Whether biological or cultural, I'm positive there are both pros and cons to hiring either gender.
Regardless, you should see my point: it's easy to get a little selective perception when you notice all the bad things about one gender. The fact that the author claims to be a woman and a feminist doesn't excuse a thing. That just means she's a woman and a feminist who stereotypes and wants to discriminate against women.
