Sure - the Constitution no where prohibited the right of State secession - therefore, that right was reserved to the States, or the people of the States.
"Learn to read you moron."

I already explained to you how it did prohibit the States from usurping powers from the United States under the Constitution but you are just trying to one-line your way out of acknowleging it.
Neither Amendment (9th or 10th) supports secession as you claim (if not then explain how) but instead these Amendments support my explanation of how they actually prohibit the States from secession.
The States had no Constitutional legal right to usurp powers from the Constitution.
I am sure that you will just spout some one-line denouncement of what I am taking the time to try to explain to you though.
