Basically you are speaking from prejudice while acting like it is science. You only want scientific proof for things you disagree with, not for your personal preferences.
> The presence of one or more older siblings at home protected against the development of asthma (adjusted relative risk for each additional older sibling, 0.8; 95 percent confidence interval, 0.7 to 1.0; P=0.04), as did attendance at day care during the first six months of life (adjusted relative risk, 0.4; 95 percent confidence interval, 0.2 to 1.0; P=0.04). Children with more exposure to other children at home or at day care were more likely to have frequent wheezing at the age of 2 years than children with little or no exposure (adjusted relative risk, 1.4; 95 percent confidence interval, 1.1 to 1.8; P=0.01) but were less likely to have frequent wheezing from the age of 6 (adjusted relative risk, 0.8; 95 percent confidence interval, 0.6 to 1.0; P=0.03) through the age of 13 (adjusted relative risk, 0.3; 95 percent confidence interval, 0.2 to 0.5; P<0.001).
Other possible explanations include: You need a certain baseline of health for both parents to successfully pursue careers. Older siblings actively help care for younger siblings. Wealthier families are likely to be generally better educated and better cared for.
Your position was openly hostile from the start. You posit that I am talking about a hermetically sealed bubble and not allowing children to have any contact whatsoever with anyone but the parents. It is hyperbolic and not a good faith engagement. Defending myself against this de facto attack forces me to sound more and more like the extremist nutcase you intentionally painted me as.
I don't plan to engage further. This is not a constructive discussion.
“Hermetically sealed bubble” was a bit of an extreme description of your (largely unspecified) alternative to sending kids out into public, but personally I feel there are many good reasons to send kids out to e.g. the park, the grocery store, the street, the bus, the library, later to occasional organized classes, etc. (e.g. so they can learn many skills including socializing with peers and the community at large) without all that much evidence of significant risks. Small children living among communities of humans pretty much inevitably get sick at least several times per year, even in relatively small and isolated agrarian societies. By most objective measures (and especially if we disregard effects from terrible diet and sitting staring at screens a whole lot) children today are incredibly safe and healthy compared to past children.
I agree it hasn’t been especially constructive, but I’m not quite sure why you were and are so wound up and negative about the conversation here.
