Christianity is an ethnicity. I’m ethnically Christian—specifically, ethnically Protestant. Every atheist and agnostic retains some part of the culture that they and their parents grew up in.

You think frat boys don’t joke about people behind their back? I’m pretty sure they do. It’s venting.

Here’s another quote you should weigh when trying to decide about Marx’s attitude toward Jews:

“Nothing compares to the misery and poverty of the Jews in Jerusalem, who reside in the Jewish quarter, between Mount Zion and Mount Moria, where all their synagogues are also situated. They are a constant target for Muslim oppression, Greek offensives and Latin persecutions. They only survive due to donation from the fellow Jews in Europe. They are not natives of Jerusalem, rather arrived from various places, drawn to the city for its religious magnetism. They suffer and pray, while looking up to Mount Moria, where the temple used to stand, daring not to approach it. They shed their tears on their destruction and exile. ” —Karl Marx, the New York Daily Tribune, 1854
