The only people who see the Westboro group and people like them as Christians, are people who want to view all Christians that way. It provides them with a way of painting every Christian with a broad brush and to justify their anti-Chirstian bigotry. There is nothing progressive about thinking we must accept every belief under the sun, except that group because "we" have decided "they" need to change.
That said, the way to fight them is to take them on directly where ever they show up. One Christian biker group is doing just that. When the westboro thugs start their chant, the bikers rev up and drown them out.
