It's not a thing. It's a lie. It's not a mistake, it's the result of years observation and study. There is no such thing as "Judeo-Christian." The values are different, the beliefs are different, the expected outcome is different. We worship different Gods. I'm not denying that it's a commonly used term. I'm arguing that it is not a valid term. Christianity perverted by jews is unfortunate, but the core belief in salvation through faith alone is still there.
