The police force shouldn’t be summarily executing people like this, you’re right about that.
But this post conveys a very strange and counter-productive understanding of what fascism is and what makes someone a fascist. Might as well be saying ‘if you think drinking water shouldn’t be privatised you are just a stalinist’. If we want to stop fascism, we have to understand what it is, and that isn’t it. If anything, a fascist furiously opposes governments murdering “right-wingers”… for pretty obvious reasons.
