Marriage is hardly a secret.
> Suppose nobody told you how difficult single parenthood is
I think you can guess. Anyway, that's not a secret either.
People are aware of these things. The options are not sermonization or censorship; that's a false dichotomy.
Being vaguely aware that “single-parenthood is harder than two-parenthood” does not count as informed.
We're openly discussing it right now.
I'm truly baffled by the idea that it isn't openly discussed.
It's not though. There's no evidence of that.
In fact, the very claim "no one wants to impinge involuntarily single-parenthood households" is itself an ironic admission that the difficulties of single-parent households are obvious to everyone.
