If you believe in seizing the means of production, cool. It's for that same end. If you believe in having patrolling militias and tanks, cool it's for that same end. If you believe in cooporation with liberals...ok...but it should be for that end. No compromise on that ideal. Make it loud and clear. Labour should be supreme over capital. The value created through human effort should take precedent over the value willed in to existence by trading on the promise of that effort. Capital should be forever beholden labour, subjugated and suppressed by it.
If anybody claims to be a socialist and compromises on this single ideal, they're not a socialist, they should be cajoned and forced in to exposing their true allegience. If they play the "bring the force in to balance" card you're talking with someone hopeless. Brainwormed by liberal right-think.
At best you can try to remind them that no superior form of capitalism can be achieved from an inferior one. And remind them that there is a voiceless mass of individuals disaffected by capitalist democracy and appeals to such is condoning a dictatorship of the electorate.
Stay strong comrades. When the tide begins to turn we will unite.
