Situation:
Evolution is a true theory. Homeotherapy is pointless. There are no UFOs. Man has landed on the moon. One man shot JFK. There is no 9/11 conspiracy, just psychopaths and heart break. There are no psychic phenomenon. Ghosts aren’t real. Tarot cards is an expensive form of Uno. Dianetics is pointless and harmful. As are the economic theories of John Maynard Keynes. The earth is round and solid. The only thing that can be read in tea leaves, is possibly what kind of tea had been drunk. The flying spaghetti monster isn’t real. There is no tea cup around Pluto.
Many people, however, believe the exact opposite of each of the above statements. Many make it their whole life’s work to prove that each of the above sentences is wrong. What they are doing is devoting their lives to utter lies and trying to convince others of their truth. You have argued with a few people on a few of these points and tried to make them see the truth, but they just retort in the end to “well, you have your opinion and I have mine.”
You feel what they meant was “truth” instead of “opinion.” 
Questions:
Should people be allowed to believe such dribble? Shouldn’t people be interested in the truth, rather than a truth? Don’t we necessarily rely on people to be factual and truth based in their opinions? What happens when our fellow citizens/friends/employers believe in such falsities? Well, is there a truth “out there” or is all truth simply the human interpretation of the world around us? Who am I to “know” what the “truth” is? What makes me so high and mighty to think that what I think is right and what others think (if it should happen to not align with my own thought) to be wrong? But don’t we all do this? Don’t we all think what we think is right is right? If we didn’t, what would be the point of thinking/supporting that thought at all? Would any of us really wish to believe ideas that we know to be false? If not, then why do so many people believe the “wrong” things? Why don’t we want to believe falsehoods? Why are we so concerned with what we think of as “the truth”? Is there something intrinsically valuable to the truth or is it merely a “useful” sort of value? Why does anyone care about why we care about the truth? Why are these questions being asked? What’s the point of asking questions? What’s the point of asking “what’s the point of asking “”what’s the point of asking “”"what’s the point of asking…
