As the sister comment alludes, how many of those 15 families are in Iran?
My professor from my graduate program and his family are all Iranian. It's no surprise that they anti-regime: his wife's uncles were generals in the Shah's army, and were "disappeared" during the Revolution. They've been living in Japan for ~40 years. Hardly indicative of the opinion of the "man on the street" in Tehran, Isfahan, or Mashhad.
Presumably you are not in Iran. Where people are getting bombed and feel the consequences of “finally [getting] rid of the Iranian regime”.
Some circles might have only pro-Trump Americans. Others might only have anti-Trump Americans. And yet your experience is all-knowing? With 15 families? Outside of Iran (presumably).
