The fire at Notre Dame cathedral on Monday prompted immediate pledges of millions of euros to help rebuild it.
On Tuesday, it spurred donations to do the same for much smaller places of worship thousands of miles away that were recently destroyed by arson.
Many users noted that while hundreds of millions of euros had already been pledged to rebuild the famous cathedral, the small churches in Louisiana were still struggling.
“These communities need to know that people care about them and what they’re going through,” Jessica Piombo, a professor who lives in Monterey, California, wrote on the campaign’s page.
“Every little bit counts.”
The campaign was posted on GoFundMe last Wednesday by the Seventh District Baptist Association, which includes 54 Baptist churches in southwest Louisiana, including the three that were burned.
The association noted that donations would go to rebuilding and replacing what was destroyed, from pews to sound systems and musical instruments.
A screen shot of the campaign’s page from early on Tuesday morning showed that it had raised $92,939 (£71,000).
That number shot upward as the day wore on, including many smaller donations.
More than 15,000 people had donated as of 11pm Eastern Time, and a spokesman for GoFundMe said the campaign had received donations from all 50 states.
Those who shared the campaign on Twitter included Hillary Clinton, the former secretary of state and first lady; journalist Yashar Ali; and Jake Tapper, the CNN anchor.
The fires occurred on 26 March, 2 April and 4 April in St. Landry Parish, north of Lafayette.
The first was at St. Mary Baptist in Port Barre; the two others were at Greater Union Baptist Church and Mount Pleasant Baptist in Opelousas, the St. Landry Parish seat.
The churches had been the spiritual homes of generations of black families.
“Let me say it like this: the only building that had any sign of any furniture remaining was Mount Pleasant,” said Freddie Jack, president of the association and the pastor of St. John Baptist Church in Ville Platte, Louisiana.
“St. Mary and Greater Union, all you see is charcoal. It’s a total, complete loss at all three sites.”
While the churches had insurance, the coverage is limited. Greater Union Baptist Church was also paying down a mortgage taken out for a recent renovation.
To complicate matters further, the new churches will have to meet stricter building codes imposed after Hurricane Katrina, Mr Jack said.
At first, he set a fundraising goal of $600,000 (£460,000), but on reflection he decided to triple that number to $1.8 million (£1.38 million), based on his own experience building his church more than a decade ago.
Whatever money is raised will be split among the three destroyed churches, each of which has more than 100 regular members, according to Mr Jack, who met with the pastors of those churches on Monday night.
“They have a long road ahead of them,” he said. “They’re a long way from full recovery, but the generosity of the people seems to be speaking volumes.”
