Just consider the words...it doesn't matter if they came from someone's pseudonym that you recognize, or anonymously.

"Let prudence direct you, temperance chasten you, fortitude support you, and justice be the guide in all your actions." -Anonymous. Would it change the meaning of the words if they could be attributed to someone like Abraham Lincoln or Winston Churchill?

Conversely: "...the personification of the devil as the symbol of all evil assumes the living shape of the Jew." -Adolf Hitler. Are these words any less offensive because they can be attributed to a recognizable name?
