On the contrary, what @rsewell said is perfectly true.
Facts are not opinions, they are not subjective, and they are not just “consensus.” They are determined through hands-on experience in situations where getting them wrong has consequences for which you could be held responsible. Consequences that, in some cases, end up with people getting killed. When your understanding of science comes from that kind of experience, then debates with people who aren’t also informed by the same kind of experience are worth diddly squat.
And if you can not accept that some things are not relative nor subjective, then you won’t last five minutes in any science or engineering based workplace.
I’m sorry if you think I’m being hard here again, but the workplace is something that I harp on about a lot in these discussions. This is because a loosey-goosey, postmodern, it’s-all-subjective-opinion attitude to facts, evidence, reason, science and the like set my own career back by well over a decade when I was younger.
