I find the "them Vs us" rhetoric to be redundant and counter productive. You're not "fighting back" because there's actually no fight. At the end of the day, it'll be about net positive and the margins, whether the approach is republican or democrat.

What I see in the UK is simply propaganda by Conservatives. They're capitalising on the populace's biases to seize power. For example:

A doctor fucked a nurse mid surgery and you've got to admit, it's hilarious because the surgery was actually successful. This was turned into an immigration issue because the doctor's from Pakistan. Do you think this is right?
