I don't see why he should. We've been discussing ways in which Wikipedia material could be made classroom-friendly over the past day or two. But key to this would be, in my opinion, uncoupling the goods train from the engine. Effectively create a vetted snapshot of Wikipedia, all set to last safe version, with certain entries bowdlerized if thought necessary.
Why should I have to that? Why don't you create a devetted snapshot of wikipedia with certian entries debowdlerized if thought necessary?
