Strange that you consider this vote legitimate, and the people of other states in convention voting to secede are illegitimate.
Oh, you noticed that, too.
Uh, yeah.
Wonder if the Tennesseeans were legitimate or illegitimate when they voted against secession, the first time out? North Carolina's public opinion changed over time, too.
Reading our man N-S is like reading a paragraph of Orwell, about quick switches in the goodthink/oldthink party line.
Notwithstanding all of the above, let me go on the record as bellyfeeling doubleplusgood duckspeakers like N-S. Oldthinkers are ungood and unbellyfeel Big Brother. IngSoc forever.

Not as strange as you treating the Southern votes for secession as binding and willing to toss out the vote in Missouri as unimportant.
I will also point out that the legitimacy of the vote isn't in question. The votes were perfectly legal. It's the manner in which the states decided to carry out those votes, unilateral secession, that was not.
