I saw someone on FB bellyaching that Debbie Wasserman Schultz in a reversal of her earlier immigration positions is now speaking out against family separations at the border.

I think that such a reaction to Schultz is silly at best. A mature left allows people to change, even welcomes it; a left on the margins is content to posture and upbraid people with less progressive views, even in instances when they shift politically in a progressive direction. Too little, too late, I guess, such people think? Or never forgive, never forget? Or is it simply a small circle mentality?
