Right, exactly! And this is a rather common theme of sci-fi of the preceding era, so of course it'll get this particular spin from survivors of a scattered leftist movement. And then as you follow Tomino's work you kinda get to see in realtime his disillusionment with both this particular conception (as the youth failed to take up the mantle of social change and instead turned their struggles inwards e.g. Evangelion) and socialism in general, until you get to Turn A Gundam which is a work about the question of whether or not humanity can ever move past the need for violence.
