FFRF is promoting its secular video message in lettering that is 56 feet wide and 29 feet high on a digital board in the heart of Times Square Plaza at 1500 Broadway.
The message is looping several times per hour from 6 a.m. to 2 a.m., and will air at least 5,460 times over a three-month period.
"With so many political developments preoccupying Americans, we don't want the constitutional principle of separation between state and church to be overlooked," says FFRF Co-President Dan Barker. "With the appointment of Judge Neil Gorsuch to the Supreme Court, the Establishment Clause is in danger.
"We're facing major threats to the First Amendment, including President Trump's proposal for federal tuition tax credits for religious schools, and his vow to allow churches to engage in partisan politicking. It's never been more important to keep that constitutional wall between state and church high and impregnable," he added.
FFRF also has produced a new red-white-and-blue bumper sticker with a timely riff.
