Notice this line and their use of the word conservative as if, somehow, these murderous a**hats have the same mental processes a conservative American does.
That's totally by design. It's part of the propaganda process. They know that just by throwing in that word many of the casual readers who are politically ignorant and gullible will make a connection negatively towards conservatism, I.E. the Republicans.
Instead of conservative the writer should have properly used the terms fundamentalist and radical.
