It's not about marriage ceremonies its about procreation; the DNA stuff is a pretty good indicator that the history of humans to a large extent involves some men having access to lots of sex whilst others got none at all. Which is exactly what people like Dwyer & Roosh, seem so irate about, as if it's something new that feminism / the modern world has done them, when in fact the opposite is true.
I'm pretty sure you're misrepresenting Dwyer there, in that he doesn't seem particularly irate about it, although I grant you that Roosh does.
