This person and the people killed at Charlie Hebdo were not fascist, so what your doing here is political misconstruction of my words.

If a person, because of their ideology, is capable of hate against others to the point of killing them, they should not get a free pass. This includes fascists, Ku-Klux-Klanners or Islamist radicals than blow themselves up, as well as those that condone that sort of behaviour.
