Don't say "There's no false middle ground" ... That is extremely assumptive and cocky.

Say what you really mean: "I only see this issue in black and white as a byproduct of my nascent understanding of the various forces at play in American politics and the motivations behind them."

You do understand that the average person sympathizes more with middle-ground attitudes, right? That speaking in extremes, except when necessary, can have the unintended effect of polarizing people? Affirming the beliefs of proponents and strengthening the resolve of opponents.

There is a reason that social disrupters who use Persona Management software aim for the middle ground when they speak. They use moderate voices that give a "balanced" view of both sides, before concluding one way or the other. Why? Because it has been shown to be a lot more effective and a greater number of people will be willing to digest the argument presented to them. Most people are on the fence and just need a little push in the right direction. They are more inclined to listen to a voice they sympathize with and less inclined to automatically become defensive and closed.

But keep up your strategy and we'll see how it goes. I'm sure your extremist "Everyone in the White House is xenophobic" argument is doing just fine.
