"Making issues visible" can be kinda dangerous in that groups that do that become dependent on those issues continuing. Also they frequently misdiagnose problems: for instance homelessness is seen as a problem of "poverty" and not "management of severe mental illness".

It's true technically that the median homeless person is not mentally ill, but the median homeless person is "between apartments" and the intractable cases, the people who are screaming on the street corners and breeding pitbulls that bite people on the Ithaca Commons are a public health problem.
