I'm not in favor of requiring hiking or certain family structures either. Serious question, is there a requirement for the nuclear family?
Let us not conflate norms and legal requirements. Where I live, there is most certainly a norm around hiking being a really positive thing that you should do, and it's associated with being higher status (local fashion trends even favor looking like you are a hiker). Not everyone is a hiker, and some people don't like hiking. But I'm okay with the norm existing, but would never support a requirement for it.
The answer depends on where you are. It's nowhere as strict as "if you have a child outside a nuclear family, you go to jail". But there may be all sorts of softer pressures in place.
Now, I don't think having such pressures is necessarily bad in all places. It becomes bad when it's a "one solution fits all" approach, and the pressure is applied even in situations where dissolving a traditional nuclear family would be in the participants' (especially the children's) best interests.
Putting myself in the shoes of black folks, I can certainly see how certain conservative initiatives cross that line.
I imagine this is in response to various conservative proposals over the years to put forth (straight) marriage as a solution to various unrelated societal ills.
