Or we've all just become hypersensitive to something that doesn't necessarily mean what you are implying.

...is what I was going to reply with, with examples of how replacing the component parts of the sentence may change how it's interpreted. Then I looked at the source article, and saw that it's a followup sentence after describing how she sued Microsoft for sexual discrimination. Regardless of how it was meant to be interpreted, that's some pretty poor awareness of context on the author's part.

Phrased as perceived. The author is probably too young to appreciate what his mother likely did for him. Becoming a parent has a tendency to change your perspective on parenthood.

I agree, that is shameful. Each year I take a week of from work to care for my 2 children when my wife goes out of town. Hardest week of my entire year!

Yep, I think it's just poor phrasing.

I just read it as "it doesn't look like she pursued her career further"

I don't think the author meant to downplay difficulty of child rearing.
