No it shows the opposite since it took a law from Congress to produce WV. Virginia had nothing to say in the matter having declared itself in secession. The people in WV were still in the Union and had every right to create a new state.
You made my point. You say Virginia had nothing to say about the secession of it’s western half because Virginia had seceded from the Union. If you want to say that there is no right to secession, then Virginia could not have left the Union. If they were still in the Union, they had a say in whether or not to split up into two states. You cannot have it both ways my friend.
