Because 100% of the time (rounded up) they are just trolling you.
I don't think so. I think that more likely rounds down to zero. Few are consciously using it as a tactic - though perhaps I'm just a dullard and all this gibberish is a conscious ploy. I doubt it, because I don't see the general level of philosophical sophistication to believe that is likely. Maybe the world is full of people pretending to be conceptually addled buffoons for some nefarious purpose I can't grasp, but I doubt it.
No, like faith, unrealism is just a philosophical immunizing strategy that they have gotten away with in some circumstance, so they use it again, like a monkey pulling a lever for a grape.
If you can get away with punting out of any intellectual difficulty with , "I just believe", "that's just logic", "it's all relative", "that's not my reality", etc., you will. As long as the get out of jail free card works, you'll keep using it. Well, maybe not you, but a lot of people will and do. I don't think they're consciously trolling.
From Being a Realist (even if you believe in God):
My mother, who doesn't call herself a theist (I think she's agnostic), doesn't even accept realism. She doesn't even agree with this:
That's little more than tautologies here. Yet it elicited an impression of being forced to believe. I know because she told me about the totalitarian dangers from such narrow thinking.
I'm happy to have finally found the root cause of our ongoing disagreement, but now, how can I deal with that? It looks pretty hopeless, but just in case, does someone have a suggestion, or should I just leave it at that? (My ego doesn't like it, but giving up is an option.)
Now I'm relieved to know that in near mode, she's a complete realist. This craziness only shows up in far mode.
