The US Constitution is silent on the issue of secession. Get over it.
Most people (the rest of us) are proud to be Americans and proud of our right to complain about what what we don't like about the country we love. That's one of the reasons that we value our US citizenship.
A few people hate the United States, but even they have to admit that they are free to leave. Some do. Some pretend. It's the "My life is a mess and it's everyone else's fault" group that gets a bit tiresome.
Geez, if I hated this country, I would leave.
