In general, I am suspicious when someone dismisses a view for being “radical” or “extreme.” There is usually sloppy thinking behind that designation. Why not just say what is wrong with the view? How for instance are we supposed to feel about “radical Christianity”? Good or bad? Does it mean Origen or Ted Cruz or something altogether different? Can’t we just debate the question itself?
The same is true in politics. Let’s say someone favors free trade and the First Amendment. Is that “radical”? Or is it mainstream and thus non-radical? Does labeling it radical further the debate on whether or not those are the correct positions?
