I feel like your reply is a vast oversimplification of the subject.

Obviously, OP didn't mean EVERY SINGLE PERSON is out for themselves. You knew what he meant and purposely took it literally.

You understanding that the world is unfair doesn't put you in a special spot. The world isn't going to change because you

So why can't OP call it out? Just because the world is unfair doesn't mean people aren't allowed to dislike that fact or talk about it. OP never indicated that he thought he was special or that the world would change for him.

This is your fault.

Ah, the "Just World" Fallacy, huh? He must be miserable because of his choices? Wrong. There are many factors that come into play when determining how and why the interpersonal relationships in one's life are the way they are. OP has every right to feel the way he feels.

" or you will always feel this way." The fact that you phrase this as a negative alternative shows that you think feeling this way is something that needs to be fixed in the first place. Seeing things as they are isn't something that needs to be fixed.

Your reply follows circular logic in that, take this for example: A girl notices there aren't as many ducks in the lake as she previously thought. She wants there to be more ducks, but she acknowledges that there aren't that many, and feels disillusioned with the fact. You advise the girl to close her eyes and imagine more ducks and then the other ducks will eventually come.

Sorry, but that's not how it works. I'd break it down and connect the example with the central argument, but I'm counting on you to be able to understand this. You assumed OP was coming on here feeling sad and angry about not getting meaningful relationships and wanting a solution in the first place, when OP was actually just trying to point out something he observed.
