More thoughts about FinCEN (Public Board)
I don't blame you for being paranoid. Considering the list of exempt businesses you posted, the Biden/Harris regime is targeting small businesses with this requirement. I don't like that they asked for your driver's license or other photo ID. Why do they need that? It looks like profiling to me.
I don't know why it would be unconstitutional, but it doesn't seem right to me either.
