The violence against a woman’s right activist, Kellie-Jay Keen, also known as Posie Parker, by radical Leftists supporting the trans agenda, is instructive. At the Quillette site, quoted below, one can find videos of the protests, as well as a photograph of Ms Parker, her face streaming blood from an assault by enraged Leftists. Parker is not doing anything which would be contrary to say second (third?) generation feminism, like the position held by J. K. Rowling, who also faces the wrath of the new radical Left for such criticisms. You see, the Left is all about pushing the boundaries once one victory is gained, and conservatives loose even more ground. But, what we see here is that without police, the Left will joyfully engage in attempted murder or murder; it was done by the Bolsheviks, by Chairman Mao et al., and is thus part of their world view, which embraces radical revolution. It is a wolf philosophy, and conservatives need to be aware of what they face.
I was not in Australia in the 1990s, but I recall seeing a photo of a Leftist thug, huge, fat, kicking a pensioner while he was on the ground at a rally for Pauline Hanson. It sums it up; he did not care if the old man died. And in 2020 in America, antifa thugs burnt down America, but Soros-sponsored radical Leftist mayors let most off. Obviously, conservatives should not respond in kind, but should be more careful in organising rallies, and take advantage of natural barriers. Situational awareness is the thing.
