If you could, how would you deprogram an extreme liberal?
How would you approach persuading a far extreme liberal toward center? What would you set as a realistic goal for a productive discourse? Would it be better attempt to do so in person rather than online?
OP asked the same question about extreme conservatives yesterday but it's not the same question, and doesn't have the same answers. Much of the right has gone further right, then looks at the left and says "they are farther away than they used to be"
