Facts vs Opinions
A common neo-obscurantist rhetorical trick that consists in coming up with an implicit dichotomy between "facts" and "opinions" (or "beliefs") in order to delegitimize dissent.
It is usually expressed in the form of slogans such as "Science cares about facts, not your opinions!"; what this trick does is to tacitally redefine the concept of "opinion" in order to only include non-factual ones (ignoring that ANY statement that's put forward in a debate is, by definition, an opinion); in this way, ANY opinion (including factual ones) can be automatically dismissed as worthless before even being uttered, while on the contrary all of one's own opinions automatically count as "facts" by mere virtue of not being referred to as "opinions".
To put it simply, the Fact vs Opinions rhetoric is just a well camouflaged way to say: "Everyone who disagrees with me is wrong, because I say so!".
