I haven't had a chance to write anything today, so I'll post a comment I've been hanging on to that I thought was insightful. This is from Tad Brennan, left on a Left2Right post. The direct link to the comment is here.
There are many senses in which this is a Christian nation--a majority of its citizens are Christian, most of its founders were Christian, it enjoys a cultural heritage that derives from Christian cultural traditions, etc. Is there any of these senses in which it would not be equally true to say that this is a white nation? Would anyone think it was politically innocuous for the leadership of one party to be vehemently declaring that it is a White Nation?
