A liberal who's nervous about not wearing a mask day-to-day anymore, despite being in good health and fully vaccinated against COVID.
The reason why a liberal becomes a demasker vary. Some, now accustomed to smugly broadcasting how sanitarily-minded they are and chiding others for improper mask usage, are still riding high and don't want the power trip to end just yet. Others are hesitant to admit just how much of their identity now revolves around liberal virtue signaling, or are worried that other virtue-signaling liberals will mistake them for anti-mask conservatives. Others still have been turned into paranoid hypochondriacs by too much cable news, overestimating the threat COVID poses to vaccinated people and thinking masks are still necessary.
