Briefly, this needs to be corrected: HAC has been spreading this pernicious myth around the internet for years.
“Historian (mainly of science) Doug Fosnow called for the USA’s “red” counties to secede from the “blue” ones, forming a new federation. This was greeted with much skepticism by the audience, who noted that the “red” federation would get practically no seacoast.”
The Gulf Coast and South Atlantic coast of Dixie is the longest coast in America with the best harbors: Houston/Galveston, New Orleans, Mobile, Tampa/St. Petersburg, Charleston, Norfolk, etc.
Note: 7 out of 10 of the busiest ports in America are on the Gulf Coast alone. The widening of the Panama Canal will also open the Gulf Coast to trade with Asia.
