Slate published a story today called Saturday’s Warriors: How Mormons went from beard-wearing radicals to clean-cut conformiststhat caught our attention. While it's an interesting rundown of how LDS culture has evolved from essentially bearded polygamists to clean-shaven business men, the tone of the article is somewhat negative towards the Church.
We like this blog post from By Common Consent, A Response to Bowman on Beards and Correlation, where the author "nit-pick's" the Slate aritcle and goes a little bit deeper into the topic.
Both are interesting reads.
