God what a slippery slope of stupidity.
Most books are written with the aim to convince the reader of certain view point. Thats hardly extremist because you disagree with the idea. All the shit lloyd writes is extremist by that definition, its just trying to convince you of a view point you agree with so its different.
I hate the wt. banning them because you disagree is wrong. Your favorite view point is next if thats what we are doing. Freedom entails responsibility and the understanding that other view points , even those you dont agree with, are the right of others to posses.
