Satire, by it's very definition identifies a person or group who, by their own acts expose themselves to suggestions of extremism and ignorance. In the materials presented on christwire, you see examples of ideas, positions, or advocacy, much like you would find on websites associated with groups or people such as Focus on the Family, Fox "News", or Sarah Palin. Remember when Pat Robertson talked about how Tinkie Winkie on the Telletubbies was gay? That would make a great post on Christwire, where we don't know whether it's real or satire.
If you read hate in this, try lightening up a bit. Even irrational thoughts cloaked in religion need to be presented as seen for what the are and how these statements can mislead.
It's satire. And you're right, either way it spreads hate. Unfortunately some people don't realize that hate is hate no matter what side of the field you're playing on and are in denial of their own bigotry. "Gee, let's combat hate by spreading more hate because our hate is BETTER!" Sigh.
