Freedom Has a Deadly Strike. Love it or leave it. The coiled rattlesnake, tied to the “Don’t Tread on Me” slogan, symbolizes American strength and defiance. First seen on the Gadsden Flag during the Revolutionary War, it reflects Benjamin Franklin’s praise for the snake: calm unless provoked, but deadly when threatened..  Today, it remains a bold reminder of the relentless fight for liberty and unapologetic patriotism.
