Hostility toward religious expression is growing in the United States, according to a new study from the Liberty Institute and The Family Research Council.
A new, called "The Survey of Religious Hostility in America" reports about 600 incidents within the last 10 years.
Liberty Institute President Kelly Shackelford said the growing hostility can lead to violence, like last week's shooting at the Family Research Council.
"America today would be unrecognizable to our Founders. Our first liberty is facing a relentless onslaught from well-funded and aggressive groups and individuals who are using the courts, Congress, and the vast federal bureaucracy to suppress and limit religious freedom," Shackelford said.
"This radicalized minority is driven by an anti-religious ideology that is turning the First Amendment upside down," he said.
The Liberty Institute and FRC will urge Democrats and Republicans to make protection of religious rights part of their party platforms this election year.
Shackelford and Perkins will present the survey and its findings Monday, Aug. 20, during the the platofrm week of the Republican National Convention.
Perkins will serve on the Republican platform committee.
"As dark as this survey is, there is much light. The secularists' agenda only advances when those who love liberty are apathetic," Perkins said. "Let this be a call to stand for religious liberty in the U.S."
"The Obama administration no longer even speaks of freedom of religion; now it is only 'freedom of worship,'" he continued. "This radical departure is one that threatens to make true religious liberty vulnerable, conditional, and limited. This is no accident and it has huge ramifications."
