The idea that there's no such thing as facts is anti-intellectual bullshit. If you can empirically establish the truth of a particular assertion, it's a fact. A fact is just a truth claim that's objectively true. If I say it's 50°F outside, that's not an opinion. I can look at a thermometer and verify that it is, in fact, 50°F. In that moment, the claim that it's 50°F is an objective fact. Facts exist, and their truth forms the basis of our understanding of reality. People who claim there's no such thing as objective truth are either ignorant of what they're talking about, or they're dishonest and pushing an agenda.
