The existence of someone's address in a phone book isn't a threat. There's not anything inherently devious about making that information public, but you can't just view that in isolation. 99.99999% of people have no use for that information. If you're publishing just that person's address without comment, you have infer the intent from the circumstances. Nobody on Parler is sharing her address to show that she's an honest politician actually living within her district. The implication of sharing just one person's home address with people who hate her is to encourage malfeasance at such location. I think this implication would have always existed.
