The New England Anti-Defamation League says there's been an increase in hate incidents in Massachusetts.
They say there are 12 hate groups in the state, including neo-nazi groups in Lowell and Cambridge.
The League's Executive Director says the current political climate is contributing to the expression of more extreme views.
He urges people not to stage a counter-protest at Saturday's Free Speech Rally at the Boston Common, as he fears a confrontation could lead to further incidents.
