how is that an opposite?
an opposite would be something everybody thinks is a bad idea until you name it
unless you’re saying people disagree with the concepts and goals of eugenics until you say “but that’s just eugenics” at which point they’re fully on board?
Most people think that Eugenics are a bad idea even if you don’t name it, which is the opposite of people actually agreeing with the ideas behind Marxism without knowing its Marxism.
but that’s not what the comment said?
Lots of people promote eugenics
people sometimes end up accidentally talking themselves into eugenics and promoting eugenics before somebody points out that they’re talking about eugenics
But it is what the comment said. It’s saying that people promote eugenics without realizing it. They do so by talking about the mechanics of eugenics without naming them.
