Filing lawsuits to stop the saying of prayers or invocations at public meetings is a major project of the ACLU and provides a flow of income to pay for the litigation. Another way the ACLU wins its cases to silence mention of religion is to file lawsuits against small entities of government -- cities and counties -- and also against small school districts, which lack enough funds in their budget to defend the case; so they just cave in and cancel their invocations or mention of religion in response to a threatening letter from the ACLU.
The last time the Republicans had a majority in Congress, a bill to protect religious freedom from such ACLU financial awards passed the House of Representatives, but not the Senate. Passing this bill is one of the things we want Congress to do if and when Republicans take control of both Houses of Congress and elect a President who will sign the legislation.
