Florida represents one of the riskiest states to visit as of today due to their Governors lax approach to the Corona virus. His loyalties seem less to his state and more to Washington. As far as New Yorkers moving out of state, while im sure some may have I notice you failed to link any statistics supporting what you allege.
Getting back to Florida, that state has always had a large population which I may add support it through their tax dollars that travel and live there. during the cold northern winters. Many Canadians also reside there all winter long. Why not single them out as well?
Americans as well as foreigners travel to Florida constantly and especially in the winter, the fact that you single out New Yorkers is a fairly obvious tactic for fairly obvious reasons and it reeks of ignorance.
