Not really, I wasn't making a comparison in action but a comparison in social psychology. In this sense, both are very similar.
A more apt comparison with the "persecution" of Joseph Smith and his followers in 19th cent US would be the "persecution" of Muhammad and his followers in Mecca. The situation of the family pictured above is not in the same category.
