Sacred Haven of Debauchery

He doesn't seem to understand anything.

No, I just don't care about your face-to-face arguments.

Do you understand that this argument can be used to prove that any creature that considers itself intelligent may turn out to be an idiot?

It seems you didn't read the highlighted word.

If different people think a person is stupid, then that's how it is, unless, of course, he's hiding his intelligence.

That's a lie.
And if we follow that logic, then the following is also true:
If different people think a person is smart, then that's how it is.
There are many different people who think I am smart (they are wrong, just like you are wrong about me being stupid).

But you, on the contrary, flaunt it as much as you can.

I'm not flaunting it, I'm just denying that I'm stupid. Sometimes I do act stupid, but everyone can act stupid sometimes.

Stupidity comes from being young. He'll grow up and become smarter. That's the logic.

Your logic is flawless and the only correct one.
You were just saying how you were considered smart as a child. You're contradicting yourself.

If your abilities were more or less outstanding, this wouldn't happen, right?

What abilities? Be more specific.
You always say that there are many different people here, and they all think I'm stupid. You won't believe it, but it's also possible that many different people are wrong.

belief in one's own uniqueness and superiority.

If you still haven't understood, I'll write it in a separate message:
I am not unique and not superior; I don't think I am, and I never have.
