I'm not sure if I'm misunderstanding but it sounds like you are implying membership of Hezbollah is deep dark shameful secret in Lebanon. The designation of Hezbollah as a "terrorist organization" is great for outside political propaganda, but the actual reality is they are a major and open faction in political life in Lebanon as both paramilitary group and political party - as is my understanding. Basically Sinn Fein/IRA.
Lebanon is very generous. They have their zones, mostly in the South, Bekaa, and a specific part of Beyrouth. It is also true they have a political wing. But they also have covert enforcers outside those zones and that is what everyone else is most fearful of. They have been involved in sectarian killings tit-for-tats, for many years. Most famously, the murder of PM rafik hariri.
So, otside of those Hizbullah zones, its actually not common to see the Hizbullah yellow flags openly displayed. Or a car bumper sticker. It is for good reason. There was a civil war before, and memories run deep.
