Secret oaths… are antithetical to the constitutional oath…
I think they should be allowed (freedom), but just like dual citizenship, you cannot serve two masters… all dual citizens and secret oath takers should be banned from any public office no matter how small.
The 16th amendment was never properly ratified and is therefore unconstitutional.
I once spent the time to review all the cases the IRS cites as proof this isn't true, but low and behold, every single one ignored the ratifcation issue and focused on some strawman…
The 16th was a core part of the plan, the other side of it being the fed (aldrich bill).
