Do you think that publications which would publish such an opinion piece or a similar one, should be banned on FR? That would exclude all of the major media source in the United States, and most in the world. It would probably even ban a great many Israeli publications.
Or do you think that the article about endangered Christian schools, by a different author and on a different topic, should be excluded because they are somewhat adjacent to each other? Was it perhaps contaminated by proximity?
I disagree with your point of view.
As you certainly know, “anti-Semitism” means anti-Jewish, regaredless of the word origin.
The writer of the article on I cited on that anti-Semitic website was absolutely not written by a Christian, even if he calls himself that. A real Christian does not equate Hamas terrorists with Christian saints. Your defense for that article is bizarre.
It is fine for you to post articles from anti-Semitic hate sites. FReepers post from Leftists sites all the time, but they rarely defend them the way you are doing now.
