Do a thought experiment: come up with a topic that is purely non-objective. Now observe that your topic is 100% bullshit. I would like a shot at it. I have been discussing this with a lot of people. The question is: "What exactly is reality?" Now this may seem bullshit at first. "Come on reality is what we can see and prove", "reality is what is 'true'", "I know it is real when I see it". These are some of the very diverse answers that I get to such a question. My personal take is, that we define something as real when a mass majority starts to believe in it. Everyone has his/her different take on if something is real or not. But for ages every body "knows" that something is real when an authority gauges what the masses believe and declares it "real". For example 1500 years back every body "knew" earth is the centre of the universe, why? Because the church said so. They also knew that earth was flat. why? Because the earth said so. We also "knew" that the electron is a particle, why? because some scientists said so or some of the experiments (which were then proven wrong) said so. So tell me, why is it that something is real once and not after some time. So isn't reality a subjective thing? Now this may sound BullShit to you but makes sense to me.
