The Neverending Slippery Slope

At what point do we get to conclude that Blankenhorn and fellow travelers (such as Maggie Gallagher) are in fact anti-gay and hateful? Or do they get to continue making the same deliberately dishonest and incoherent mechanism-lacking arguments forever, without having their motivations called into question?

One of my fondest memories working as a Cato intern was when I got to heckle Gallagher’s anti-gay claptrap at a lecture she gave to the Heritage interns. Heckling bigots is fun.
