I don’t know but had just wondered. I would think conservatives would have more kids than white liberals. The minority population I’d guess is the opposite.
But that’s just guessing
I think the concept of “conservative” has been hollowed out and the label drained of nearly all significant meaning by decades of exposure to, and unwittingly falling into a pattern of, societal and personal effeminacy. The practice of it in 2020s America is downright militant, and its scope is at the level of a highly influential industry. Masculinity, crucial to the living out of conservative ideals, has seemingly been outlawed in polite society, with the average wife of a supposedly conservative man in certain areas of the country, if not yet all, typically being the final executioner of those tendencies in his makeup.
