Five years ago, members of the Mormon Church poured $20 million and thousands of volunteers into Prop 8, which banned gay marriage in California. But now Prop 8 is dead. But the collateral damage from the $80 million spent by both sides on that brutal campaign remains.

On Sunday another step toward reconciliation happens when 150 Mormons — led by San Franciscan Mitch Mayne — will be marching in Sunday’s Pride parade behind a banner that says “Mormons for Marriage Equality.”

In our story in Sunday’s Chronicle, we talk about how a small group of Mormons are trying to reach out to the LGBT community — particularly the LGBT kids in their families. They’re being helped by San Francisco State University’s Family Acceptance Project. The research organization published booklet in how Mormons can talk to their LGBT kids — in the language of the Mormon culture — and shows them how to help. Check it out here.

The Project’s director, Caitlin Ryan, also just produced a film about a Bakersfield family who obediently followed their church’s directions and campaigned for Prop 8 back in 2008. But that was before they knew their now-14-year-old son was gay.A trailer from the 23-minute film, which was just screened at San Francisco’s Frameline festival for LGBT films, is set to hit the festival circuit soon. More important, perhaps, it will be screened at a major Mormon conference net month.

Also marching in Sunday’s parade will be Wendy Montgomery, the mom in that film, accompanied by her 14-year-old son Jordan and her daughter. For more, check out out Sunday’s Chronicle.

Wendy Montgomery also will be marching with today’s Mormon contingent. She will be carrying a sign that says, “This Mormon mom loves her gay son!”

Here’s a clip from the film:
