I always enjoy seeing this line of reasoning because it seems completely unique to people in tech. A group is not a set of individuals, or at least that's what's meant when non-tech people talk about them. When the parent says "half the country" they don't mean "the set of all people who worship the police is around 150 million" they mean "the political body that is backed by around half the country has chosen to adopt as a core tenant a largely uncritical support of police."
