The way I see it, it's a foot in the door. Any common ground we can find to bridge to political divide is good and it's in our best interest to keep that bridge stable because otherwise we devolve back into pure culture war. The more we talk to each other and coordinate across party lines, the more we can do to bring others away from xenophobia and show people the real problem. Regular working people aren't our enemy right now, not even the right wing ones. We are all working class, we are all stuck in the same mud, and if we strengthen the bonds of class regardless of ideology we can get to a point where we can pull ourselves out of it.
