There are basically three strategies for social change: 1) Be an ungovernable minority who it's too expensive to oppress, 2) win at the ballot box via technical majorities, 3) impose new social norms via holding an overwhelming majority.
Anarchists have historically focused on 1 with forays into 3. But social justice focuses on 3 with forays into 2. There is a tension there.
You left out "lead by example."
"It is the historic mission of the working class to do away with capitalism. The army of production must be organized, not only for everyday struggle with capitalists, but also to carry on production when capitalism shall have been overthrown. By organizing industrially we are forming the structure of the new society within the shell of the old."
