The Reverend speculates that environmentalists may have been offended by more historically accurate scenes that could have been included in the movie, such as coal being shoveled into the steam engine.

This perspective seems to indicate a fundamental misunderstanding of what it means to be environmentally conscious.

To clarify, so-called environmentalists are not typically upset by the accurate portrayal of historical practices in modern film. They tend to be more offended with the continued use of energy sources like coal that have long been known to pollute the air with carcinogens and greenhouse gasses.

Just sayin’.
