Each to his own. It seems you "choose not to be" a father and thus the effects described don't apply or make sense to you. I have seen the changes described in this article myself and it only confirms what I have seen. I don't think the stay-at-home-dad thing is a bad thing or even being forced upon men in general - hell I hear more men arguing *for* the right to be a stay-at-home-dad than against it. I think you're seeing ideologically charged language where there is none; perhaps the mention of a same-sex couple or the mention that the effect is triggered differently in women has skewed your opinion.
Just to be clear, I am certainly not a feminist. I'm not narrow minded enough for that. I'm an egalitarian.
(clearly my opinion)
