RJJensen, or Richard J. Jensen, is a retired professor of history and at least 70 years old. He’s very conservative and runs several conservative online groups. Those like Jinxmchue and Ed Poor who like to imagine they are intellectual could find a real intellectual challenging. 
RJJensen was originally a prolific contributor to Wikipedia and later served on Citizendium's Editorial Council.  After a disagreement with CZ's founder, Larry Sanger, he moved to Conservapedia and became very active.
Prof. Jensen's knack for historical fact led him into several confrontations over TK's cut n' paste citations from cp:Glenn Beck, most notably over cp:Margaret Sanger and cp:Herbert Croly. An editor noted on his talk page,
I was wondering why you continue to associate with Conservapedia. Given your extensive resume, you are obviously more qualified to write about history and politics than the likes of TK, Andy, Karajou, and pretty much every other Admin. And yet recently, in your quest to make Conservapedia more respectable by removing some blatant liberal bashing, you are being challenged by TK and others. When is it time to say that enough is enough? Your knowledge and expertise would be better appreciated elsewhere, where you could write with intellectual equals. I don’t want to get into a bash fest here, but how can you contribute to a site that puts more power in the hands of intellectual black holes like Ed Poor and Conservative than well educated and intelligent writers like you or KSorenson? Please let me know.

The comments were, of course, oversighted without his consultation or permission by another sysop. RJJensen ceased editing altogether that same month after Conservapedia founder Andy Schlafly, unilaterally and without discussion, deleted Prof. Jensen's entry on cp:American Jews. He was formally de-sysoped on 19 August, 2011.  Since January 2010, his focus has shifted back to Wikipedia.
