In attendance at the event was Alex Khasnabish, agitator, activist, university professor and anti-fa supporter - wearing his anti-fascist tshirt when the Cornwallis statue was also under attack - the statue was eventually removed...
Attacking "white wellness ideas" seems to be SJW Alex's thing..

National Citizens Alliance event in Halifax attracted a crowd of protestors..

Some videos at NCA's youtube channel from the recent event to promote their political party which was met with violence and "very loud protest" on the street.
The yelling and anger of the protestors would indicate they are the corrosive force; not the four men gathering to promote ideas with the NCA... I am sure the police realize exactly what tactics the 'protestors' use and how they are networked.
