Donald Trump Jr. on Tuesday morning decided to re-up a column from an anti-Muslim, anti-immigrant British activist blaring that “Western woman will be sacrificed at the alter of mass migration.”

After tweeting an anti-immigrant message featuring a white supremacist meme on Monday night, the eldest son of the GOP nominee tweeted:

Europe’s Rape Epidemic: Western Women Will Be Sacrificed At The Altar Of Mass Migration https://t.co/BkguApQqvQ via @BreitbartNews — Donald Trump Jr. (@DonaldJTrumpJr) September 20, 2016

He linked to a 2015 post from Anne-Marie Waters, a British activist and member of the fervently anti-immigration UK Independence Party, which she penned for Breitbart’s London offshoot.

In the post, Waters recounts being sexually harassed and intimidated by “Middle Eastern-looking men” across Europe to set the stage for her takedown of “suicidal” immigration polices that she says allow Muslim men to rape white women.

“In England, it’s been rape after rape – tens of thousands of young British girls are brutalised, tortured, beaten and raped by organised gangs comprised almost exclusively of Muslims,” she wrote.

In Germany, Chancellor Angela Merkel’s immigration polices “opened the door to the rape of German women,” Waters wrote. She went on to claim rape, sexual assault and “forced prostitution” are “rampant within the refugee camps in Germany.”
