That’s an idiotic petition. That’s like putting out a petition declaring that the Moon is made of cheese. Pointless.

"Mr. President, please sign an executive order such that each American citizen who signed a petition from any state to secede from the USA shall have their citizenship stripped and be peacefully deported,"

Hm, what an interesting -- in the grotesque sense -- set of premises here.
1 - The assumption that the state can unilaterally strip citizenship; this means that all rights and privileges attendant to citizenship are dependent upon the government.
2 - The assumption that political speech may be punished under laws which congress is prohibited from enacting.
3 - If not #2, then the assumption that a single person, the president, has that arbitrary power.
