the Soviet Union crushing Hungarian workers in 1956
That’s where the term comes from. Before that, it was common among the western left to support the Soviet Union and don’t allow criticism. When they crushed the Hungarian workers, most western leftist redrew their support, except for tankies. That’s where they got their name.
I don’t know how supportive this version really is. It’s like “I’m a gender dysphoric trans boy and I want to look like a boy” – “No, you are a beautiful girl. Facts don’t care about your feelings” but maybe I’m over analyzing
Idk but it would make sense since snails have both sexes in each individual and can decide each time. Which is kind of super fluid.
Some fish can change sex once in life so that might fit better. But that’s a lesser known fact I guess. The Nemo movie where they finally change to female is yet to be released.
