Some of the antifascists in Australia have had success with YARDing (Yelling At Racist Dogs): "How to deal with alt-right pests at rallies".

Demonstrating to these idiots that they're outsiders to the communities they're targeting is, you picked the right word, demoralising. One of the main neo-Nazi organisers here (Joel Davis) made a speech to the UK Patriotic Alternative, quote "You guys might get demoralised sometimes when you do a demonstration and there's fifty of you and there's two hundred antifa- I'm not saying that's happened, but I don't- I don't know all the details, but I've been in experiences like that where I've gone to protests [...] and there's ten of us and, like, two hundred communists. And it feels like shit. i-it's horrible. It's horrifying."
