The title of the article was relevant but misleading. It was not much about the ability or not of men to parent children, than on the perception of their abilities and expectations (or lack of) to do it from the society POV.

Your experience is supposed to be exceptionnal, and men really investing themself in parenting is not the expected behaviour. And in my experience taking a long parental leave for a man can be more or less difficult, but it is also surprisingly awkward (you're just slacking are you? jokes abunding) and needs a lot more justification. It seems to be changing, but so slowly.
