Certainly very ironic. But is this line of argument incorrect?

E.g. if I said "I don't believe in the Holy Book because in verse 7 it says that one cannot trust anything written in any books". Isn't that an analogous reasoning?

I think these examples/arguments are ultimately about exposing a liar-paradox statement, and when you can show such a statement you have proven that something isn't right.
