Multiple incidents around the country sparked Saturday's nationwide gay kiss-in, according to its organizers.

In San Diego, for instance, men and women puckered up to protest the passing of Proposition 8, California's gay marriage ban narrowly approved by voters in November.

But kisses were being traded in Salt Lake City to protest the Church of Jesus Christ of Latter-day Saints' (the Mormons) June detainment of two men after the pair kissed on church property. Others cited the July police ejection of five men from a Mexican fast-food restaurant in El Paso, Texas because two of the men shared a kiss.

“2009 may be remembered as the year same-sex marriage took hold in the United States,” gay activist David Badash said in a post announcing the event. “Sadly, it may also be remembered as the year gay couples were repeatedly arrested – for kissing.”

“Enough is enough. It's time we call these 'peace officers' out. It's time we showed them love can't be stopped. It's time for a nationwide kiss-in,” Badash added.

San Diego protesters gathered in front of the Manchester Grand Hyatt. The hotel is being boycotted by gay rights groups because owner Doug Manchester donated $125,000 in support of Proposition 8 while it was being gestated by anti-gay groups. Manchester is often credited for creating momentum for the measure when its future looked dim.

About 60 couples attended the kiss-in, smooching between American flags and boycott signs.

Protesters in Salt Lake City were puckering up for the third time this summer. Tempers flared during a kiss-in last month when anti-gay protesters clashed with pro-gay kissers.

But demonstrators on Saturday pulled off their public displays of affection without disruption. Some warmly kissed their children.

“The seeds have already been planted for the biggest cultural shift GLBT people will have ever experienced,” actor and activist Charles Lynn Frost told the crowd, estimated at 150 people, the Salt Lake Tribune reported Sunday.

As home of the Mormon Church, Salt Lake City remains at the epicenter of the gay kiss movement. Mormons donated millions of dollars and thousands of hours – at the behest of church officials – towards passage of Proposition 8. In June, Matt Aune, 28, and his partner Derek Jones, 25, were cuffed and detained by church security guards for kissing on the Main Street Plaza, private property owned by the church. Police cited the pair for trespassing, but the city later dismissed the charges, saying the church failed to properly notify the public.

Protesters locked lips in other cities as well, including Atlanta, Washington D.C. and Toronto.
