Well, arguing is an action of supporting two different worldviews, and one deconstructing the other. You must win, but be gentle, this is their world.

Something like that. Methods differ from person to person, but I see the best way to convince people is propaganda of the deed. Once you find like minded people and agitate, you'll start slow, but as the contradictions sharped people will begin to 'wake up' and choose socialism. Its a very slow buildup that changes into a very frantic political battle.
