For neo-Nazis and Klansmen in Charlottesville, one means, a torch-lit parade meant to intimidate by evoking bygone days of racial terrorism, was deeply objectionable; more importantly, their end, spreading white supremacist ideology in service of a future where racists can lord power over Jews and people of color, is abhorrent.
Antifa is more complicated.
Some of its members employ the objectionable means of initiating extralegal street violence; but its stated end of resisting fascism is laudable, while its actual end is contested. Is it really just about resisting fascists or does it have a greater, less defensible agenda? Many debates about Antifa that play out on social media would prove less divisive if the parties understood themselves to be agreeing that opposing fascism is laudable while disagreeing about Antifa’s means, or whether its end is really that limited.
