There is no longer any doubt
I guess someone at the beach must have called Mrs Alito the c-word too. The NY Times reports:
Last summer, two years after an upside-down American flag was flown outside the Virginia home of Justice Samuel A. Alito Jr., another provocative symbol was displayed at his vacation house in New Jersey, according to interviews and photographs.
This time, it was the “Appeal to Heaven” flag, which, like the inverted U.S. flag, was carried by rioters at the Capitol on Jan. 6, 2021. Also known as the Pine Tree flag, it dates back to the Revolutionary War, but largely fell into obscurity until recent years and is now a symbol of support for former President Donald J. Trump, for a religious strand of the “Stop the Steal” campaign and for a push to remake American government in Christian terms.
Three photographs obtained by The New York Times, along with accounts from a half-dozen neighbors and passers-by, show that the Appeal to Heaven flag was aloft at the Alito home on Long Beach Island in July and September of 2023. A Google street view image from late August also shows the flag.
The photographs, each taken independently, are from four different dates. It is not clear whether the flag was displayed continuously during those months or how long it was flown overall.
Justice Alito declined to respond to questions about the beach house flag, including what it was intended to convey and how it comported with his obligations as a justice. The court also declined to respond.
What is the “Appeal to Heave” flag? It’s a revolutionary war flag that has been appropriated by the radical right in recent years:
In the 2010s, the flag became appropriated as a religious and political symbol by some conservative, nationalist, and Christian nationalist activists within the United States…In 2021, some Trump supporters carried the flag during the January 6 United States Capitol attack.
By the way, in 2023, Mike Johnson, newly elected Speaker of the United States House of Representatives, hung the flag outside his Congressional office.
