Worcester is not Boston, not by a long shot; entirely different topography, culture, patois and climate. Brutal snowfalls, Houston sticky in summer.

I couldn't watch all of that.  The young man being interviewed is obviously mentally disturbed.  Anders Breivik by definition cannot be considered a White Nationalist, because a racial or ethnic nationalist of any race would not kill children of his own race or ethnicity.  Even if the children espouse a belief in multiculturalism, they're not legitimate targets because of immaturity.  There is always the chance that children will reject multiculturalism when they are older.  The more paranoid members of the White Nationalist Underground believe Anders Breivik to be some sort of plant or patsy; the less paranoid members have written him off as a nutcase.

This is like me asking you to delineate between the south side of the Thames and the north side of the Thames for accents in the east side of London.  Meh.
