You don't label it as such (as subjective), and I think this is required more when contradicting a previous opinion, with a hint of accusation (i.e. it would imply people using the term would be guilty of something offensive). The comment previous includes the words "not strictly"; meaning "This isn't always what this means, but it can also mean this".

How is shunning "academic" evidence addressing the issue? If it's complicated, there is a need more more precision, not less.
I won't declare this to be selection bias, but I won't assume it's not either. Testimony is a weak form of evidence. Maybe strong or persuasive evidence isn't what you intended to communicate in your comment, but I feel you need to provide something like that in a personally accusatory post ("No, stop that line of thinking. Please."), because it makes someone look bad without strong justification.
