Earlier quoted context omitted.
I’ve seen more of this type of rhetoric online in the last few years and find it very insidious. It subtly erodes the value of objective truth and tries to paint it as only one of many interpretations or beliefs, which is nothing more than a false equivalence. The concept of being unbiased has been around for a long time, and we’re not going to throw it away just because a few people disagree with the premise.
There is no rhetoric here, it’s just literal truth. There is no implication of equivalence or any statement about the value of objective truth. Any position is a bias. A flat earther would consider a round-earther biased. That doesn’t make them equal positions.
That’s bollocks. The Earth is measurably not flat.
You start from a position of moral relativism and then apply it to falsifiable propositions. It’s really not the same thing. Some ideas are provably false and saying that they are false is not "bias".
