The argument that we should let neonazis/etc. parade their ideas around in public so that the world can see them for who they really are has become a lot less convincing because neonazis have refined their tactics (see e.g. "boots for suits"). They are not parading their hatred. Today they start with softer language, focusing on the supposed struggle of white people in America, how non-white people seem to be getting a leg up at the expense of white people, etc. Once they have drawn someone in, someone who for whatever reason found that the "great replacement" or "white genocide" theory resonated with them, they start to give the "explanation" for all the problems -- out of sight, away from people who might criticize them.
