The truth is not what we want.
That isn’t the point. The point is that the truth itself has no power.
Say that the government finally decides to act on the decades of building up a false narrative of incels as terrorists. Anti-incel kill squads are now deployed and given full emergency power under the pretense of wiping out the “domestic terror threat” of incels.
You are found, rounded up and made to face the wall. The officer in charge tells you that you are an incel and therefore a terrorist, your sentence is death. The truth, however, is that you are simply a below average man who has never had sex. The truth is that incels actually statistically commit far less crimes than most other demographics, most notably niggers, normies, and Chads. You explain this to him. You explain that you’ve never even kissed a woman, much less posed a threat to her.
Will the truth descend from heaven and rescue you from your execution? Will the truth stop the bullet tearing through your skull? Will the almighty truth change the fact that your brains are now splattered on the wall?
If you say that 2+2=4, and I say that it’s 5, and so I kill you for it, who was right? The answer is that it doesn’t matter. You’re dead and I’m alive.
In society, the truth has no inherent power, force and might are all that matters in practice. As for your point about building houses, you fail to account for the fact that in this hypothetical, humans are struggling against physics and nature itself. If a man says that 2+2 is 4, and another man says that it’s 5, and the second man is killed for it, then the first man emerges victorious. However, if physics and reality says that 2+2 is 4, and a man says that it’s 5, thus causing him to make a fatal miscalculation that results in the house collapsing on him and killing him, then physics has proven itself stronger, and has emerged victorious.
At the end of the day, whoever is more powerful, be it a man or nature, will emerge victorious, regardless of who is objectively correct.
The truth itself does not change, that is correct, however it doesn’t matter. Think about this, if you’re right and I’m wrong, and then you’re dead and I’m alive, of what benefit was being correct to you? Does it make you any less dead? If I kill you for being correct, and if physics kills you for being incorrect, under which example are you less dead? Neither, the outcome was the same, you knowing the truth was irrelevant to the outcome.
