The common opinion of the several online buddies who've commented to me by IM about the Provo flag story:

Struck me as incredibly amusing, knowing the homophobic views of Utahns in general and residents of Happy Valley in particular.
Must be the rampant scholarship going on at BYU. Free exchange of ideas and all that, keeps them awash in new thinkin' all the time!
