Let me preface this by saying I didn't read your whole rant. While pink is my favorite color in certain contexts, it's not a good choice for the text of an essay.

Like Ragoczy pointed out, please don't attempt to characterize some 300 million very different people as a single entity. The US has some states the size of independent countries; referring to all Americans as one is like grouping the English and the French as "Europeans."

Yes, evangelicals are a stain on society. Unfortunately, they're a very local minority, driven by fear and faith, and many hold positions of power. These are people who have exploited a noble system of government for their own gain, and have dug in to a point where nothing short of bloodshed can dislodge them. I realize this sounds extreme, but it's reality. At the root of the problem is religion; attacking one's beliefs, no matter how incredible, serves only to strengthen the holder's resolve.
