Whoever, owing allegiance to the United States, levies war against them or adheres to their enemies, ...
1.- Does he owe allegiance to the United States? How is that even defined? I don't see how "adoctrinating children to the pledge of alliance" counts, since it's, well, indoctrination, not allegiance.
2.- Did he levy war against them? To my understatement, he is not a sovereign representative and even if such he has not filed a declaration of war.
3.- If not, what enemy of the US did he adhere to? The only reasonable interpretarion I can see here is that he adhered to The People, and thus legally the US State considers The People of the US an enemy.
You better give it a good lock code!
