It's a very erroneous strategy to try to push the Russian opposition to unite. First of all, the opposition is addressing different parts of Russian society that have differing points of view. And besides, a united opposition is a nice big target that the authorities have a much easier time fighting. And besides, resisting an authoritarian regime with an authoritarian opposition merely means that, in the event of victory, you're just doing yet another round of the same old, same old.
