I have a few questions about NPOV:
Is it POV to classify something as a pseudoscience (and say that it's definitely not true)?
Not if the something is truely a pseudoscience, as for example [[astrology]].
Is it POV to say that communism never works in practice? (or something similar)
No, just a simple fact-based observation.
Is it POV to only list some of the facts (by accident or on purpose) leading someone to believe one point of view?
Yes, a lawyer's trick.
Is it POV to use words that can be '''interperated''' as insulting?
Yes, Dummy!
