I've posted diaries at DailyKos, TPMCafé and OpenLeft calling for action in response to a letter scheduled to be read from the pulpits of the LDS Church in California on June 29th. Many others have expressed similar sentiments and made the same appeal.
The AP reports that these calls for political displays are rankling some Mormons. Of course, the letter itself is also rankling plenty of Mormons. In any case, the AP's reporting would seem to be confirmed by this post at Mormon blog Nine Moons.
As we gear up for this action, we've found a handy tool for finding LDS meeting locations and times, provided courtesy of the same folks who drafted the letter we'll be protesting this Sunday. Just type in your city or postal code and it'll do the rest. Please show up and show some love this Sunday (or if you're LDS and attending this Sunday, walk out and show a little solidarity with your gay brothers and sisters).
