Your premise that conservatives
alone can’t (or won’t) use the term socialist (or socialism) correctly falls apart when terms like democratic socialism (also used by many non-conservatives to describe mixed economies) are deemed perfectly acceptable.
Describing things like M4A (HR 676) as being socialist are correct since M4A is a single-payer (100% government funded) system which requires all participating (medical care) providers to be either public or non-profit is entirely correct.
What makes the ‘Nordic Model’ appealing to many is that the public/private mix within those economies is 30% or more government owned or controlled (aka socialist) and they have a generous social safety net and public pension system with well-funded public services in a relatively high-tax economy.
