If there are enough people to win a civil war, thinking there are enough to accomplish the same peacefully.
Organization, the right words and methods would be the tough part...the left is well versed in those.
There is no winning peacefully. Our opponents are willing, even eager to kill as many of us as it takes to cement their eternal control. What will you offer them to accept you living free of their control? When all they want is to control or kill you, you have nothing to negotiate with. It is an existential fight, and one must needs kill the other before there is peace.
Additionally, it is damn hard to sell the uncertainty and hard work of liberty to folks being offered rainbow stew and easy living.
