::::::: Steve you seem to be missing the primary point: Regardless of your theological views of J4J and Messianic Judaism, there's no way a claim that some members of a large group say something is a BLP violation. Under that logic the statement "some Wikipedians are stupid jerks" or "some Americans are criminals" would be BLP violations without sourcing. Again, this is completely aside from the fact that you are making a claim about the Christian attitude towards Messianic Judaism. (If there's any disagreement by "fundamentalists" on this matter I'd be very interested in seeing a citation it should presumably be included in the article). But the bottom line is that saying something about unnamed members of a large group is not a BLP violation.
