They are not particularly cowards. They do hold up an anti-abortion, anti-infanticide, anti-euthanasia line on the Left, which take a certain amount of moral courage.
Nor are they stupid (although this was a particularly stupid article). They are open to Left-Right dialogue and engagement, which preserves them from the sheer thud-headed doltishness we see so much of on the Religious Left.

As dear old Cicero said long ago, "Cui bono?" ("Who benefits?" or in free translation, "Follow the money.")
