It's a problem that your GetReligionistas face all the time: Many readers do not understand that columnists and opinion writers play by different rules than journalists who write hard news for traditional news organizations.
Yes, it doesn't help -- see this file on what we call "Kellerism" -- that many important mainstream journalists who should know better are blurring the lines between what many textbooks would call the "American model" of the press and the older "European model" which embraces advocacy journalism. This happens a lot when journalists cover debates about doctrine, sex and law.
As a rule, GetReligion focuses on mainstream, hard-news coverage of religion. However, from time to time we pass along "think pieces" that focus on subjects directly linked to religion-news coverage or topics that we think would interest our readers. Several readers sent us a link to a recent First Things piece that takes a critical look at a recent Huffington Post piece -- about same-sex marriage, of course -- that, according to a man interviewed for the HP piece, veered into creative fiction.
This raises a crucial question: What is the HP these days? It often contains serious news reported using a straight forward , hard-news approach, but it is also packed with opinion essays and advocacy pieces that reflect its liberal editorial point of view. So, can you criticize a liberal columnist for writing a liberal column? In this case, the First Things writer is alleging far more than mere bias.
