But I for one don't use scientism as an insult. Just for clarification of debate.
Something to be used as an insult is very subjective. I gave the example of punkofnice and nihilism. Punk admitted to be a nihilist but at the same time he said doesn't like the label.
My position is Catholicism which is an "ism" too. I don't understand why some people are so sensitive about being properly defined.
There's no such thing as a neutral/unbiased/objective position.
Objects can't be accessed without a subject.
So a proper discussion requires clear definitions by the subjects.
