Why aren't there more resources for debunking Judaism?

Yesterday I asked exactly why people don't just debunk Judaism instead of focusing on Christianity and Islam. This lady named Cher Was Here JPA accepted the challenge and gave me a few resources on Jewish theology to study. I've looked over those, but I just can't seem to find anything about it from (legitimate) non-Jewish sources. Why isn't there anything like the wealth of information for critically examining Christianity and Islam?
