There are a few (helpful) signals that people send, when they've made an emotional decision and are merely trying to justify it after-the-fact. Using emotionally-charged cliches and strawmen ("nanny state") is a large flashing sign of that type.
You really shouldn't expect such a position to have any logical or philosophical consistency. Nor should you expect it to be receptive to data. If one of their pet justifications is refuted, the conclusion will remain iron-clad; they'll simply fish around for a new justification.
