Sounds like she's trying to stretch the 7,000 number into 25,000.
I don't even believe the 7000 number. 7000 from Dearborn, which also has a large Christian Arab population, including a huge Antiochian parish, does not translate into 7000 Hezbollah supporting Shi'ites, even if there are a lot of dual-citizenship Shi'ites in Dearborn. I'd lay better than even odds that some, and not just a handful, of the 7000 are from that parish and visiting family or Balamand Seminary.
