Amanda Marcotte in Salon:

Donald Trump's new lie is a real turkey: Now liberals are waging war on Thanksgiving!
 Not content with the mythical "war on Christmas," Trump now claims that liberals want to cancel Thanksgiving

Also Salon.com, at various times:

• The destructive legacy of the first Thanksgiving: How Europeans hurt the American diet
  Colonists' food and policies hurt Native peoples' health. Now Native communities are taking their food ways back
• Thanksgiving, a day of mourning for Native Americans
  Native Americans are still here — and Thanksgiving is a day of remembrance and activism for us
• Thanksgiving? Instead, let's atone for the genocide that was committed
  And not only committed, but condoned, by the very men we idolize as our "heroic" founding fathers
• Why have millennials stopped celebrating Thanksgiving?
  Revisiting the racist history behind Thanksgiving
• Our Thanksgiving responsibility: Native Americans, honest history and the simple power of remembrance
  It has taken us hundreds of years to come to terms with the damage done. True memorials liberate us from forgetting

Salon.com is famous for denying the War On Christmas (see here and here) but also posted this in 2012:

There really is a war on Christmas!
And it's being fought by some of the bravest atheists in the country, nonbelievers in rural areas and the heartland

At the time I wrote that the story made it explicit

that in Red State America, Christophobes are more militant because they’re a minority, where as in New York and New Jersey, they rule.

But seriously, grenades? Hasn't Salon heard of the "Civility Movement"? Even in America's supposedly metaphorical War On Christmas, arson of nativity scenes is not unknown,  and vandalism is epidemic.  In a world where Christian churches are bombed and burned on a weekly basis,  Salon is going beyond anything the left ever imagined Sarah Palin was guilty of terms of violent imagery.

Swearing off the rhetoric of violence

Can't we agree to stop urging supporters to "reload" or pursue "Second Amendment remedies?"
