One point of leverage that I use is MLK, who libs pay a fair bit of lip service to.
"First, I must confess that over the last few years I have been gravely disappointed with the white moderate. I have almost reached the regrettable conclusion that the Negro’s great stumbling block in the stride toward freedom is not the White Citizen’s Council-er or the Ku Klux Klanner, but the white moderate who is more devoted to “order” than to justice; who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice; who constantly says “I agree with you in the goal you seek, but I can’t agree with your methods of direct action;” who paternalistically feels he can set the timetable for another man’s freedom; who lives by the myth of time and who constantly advises the Negro to wait until a “more convenient season.”
The ruling regime always sterilizes the radical figures it cannot ignore, which is a weakness I try to exploit. Even republicans will quote MLK, so I try to use their lip service against themselves to drop truth bombs. And like you said, it’s food for thought. I’m not debating anyone, just stating facts. Just trying to sew seeds where I go.
