But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.
"new Guards for their future security" refers to forming their own government, the purpose of which is to safeguard the aforementioned inalienable rights. If "throw off such Government" is really the strongest call to revolutionary violence you can point out, I stand by my point.
It is absurd to assume that "throw off such government " means anything other than by forceful (violent ) means, especially considering the authors subsequent actions.
