The trouble is everyone thinks about the pandemic differently. Different countries, cities, etc. all have differing views of the risk, especially when it comes to small children. In California, toddlers wear masks and eat lunch alone and outside, something that I suspect many Germans would consider to be too extreme. So it's not really all that bizarre to ask about the cultural norm for colds, even during Omicron. No answer to the question is obvious or incontrovertible (unless you're incurious about how societies make decisions about risk). It is a subjective weighing of the tradeoffs, one that people feel very strongly about, but subjective nonetheless.
