"The Gospel writers nicked stories from each other verbatim "
That's a phrase I found in a Facebook comment thread. This is how people like to defend plagiarists. Plagiarism is not so bad, because Jesus, Shakespeare... It pretends to be historically savvy but is quite the opposite.
What bothered me most in people defending their own plagiarism was the appeal to their status as victims and the use of the vocabulary of self-love and empowerment.
