Personally, I think even paying attention to them is what they want. Political movements only make headway when they have airtime. Hating them is a dream come true, so is attacking them, Look how much money the Phelps family has made over the years simply by being hated.
They are not worthy of my hate, they disgust me, yes, but they are small, insignificant, impotent and loud. The trick is, no matter what they spew, treat it with the utmost contempt it deserves, and focus on things that are, in some way, involving the use of our higher cognitive functions.
