• Democrats refusing to acknowledge Barack Obama's appeal to unpatriotic donors and supporters
• materialists refuse to address the impossibility of material explanation for migration and homing
• evolutionists refuse to address the lack of a plausible evolutionary path for the whale
• liberals refuse to address how socialism destroys productivity
• abortionists refuse to address the undisclosed harm to the mothers who have abortions
• Advocates of the global warming theory refuse to consider any scientific evidence which shows that natural causes have always had a greater effect on terrestrial air temperature than human activity.

• I've never seen that in the Bible!
• I've never heard my homeschool teacher daddy say that!
• If you believe that, I bet you oppose school prayer! 95% chance!

• I'm not interested in that, because it might go against my preconceived notions, and I don't like going outside my comfort zone!
