Since much of the impact is subconscious, the people who it is happening to are not in the best position to evaluate it.

That sounds like an extremely convenient way to discount the experiences of any and every man who's stayed at home with his children, and never felt diminished. Naturally it follows that it's also a convenient ploy to discount their spouses who don't think they're diminished either. I'll be uncharacteristicly blunt, I think it's bullshit.

Not really - what I am saying is true, though I have explicitly said it is not a factor in all cases.

I'm glad it works for you, but that being said, what I said is true in many cases. That you feel it hasn't been a factor in your relationship is a good thing.
