I hate the Mommy Wars, especially the defensive responses that women think they need to have, but what I really hate about this particular article is the completely rude way that this guy is "defending" his wife. I would be irate if my husband acted like this. I'm a strong woman and I don't need my husband to defend me, thank you very much. I'm assuming from the tone of the article that she enjoys being a SAHM and was involved in the choice to stay home. I don't understand why if he had to say something, he couldn't have said: "Jane loves being at home with the kids, and we are so fortunate that she is able to do that." End of story.
I work full-time and have heard my share of "staying home is best" lectures from everyone from family to strangers. I think it is extremely rude to force your opinions on others, but that's no excuse to be a jerk in return. "I love my job, and I'm so fortunate to be able to be a/an <insert job here> and a mom." If they won't shut up, I excuse myself and walk away.
