1) The stretch in the comment I replied to was referring to calling the area below the Topkapi Palace in Istanbul as belonging to Eurasia. I simply pointed out there is no stretch in there, since it does objectively belong to Eurasia, which unlike Middle-East is far of a more settled geographical definition.
2) In my other comment you are probably referring to, I simply pointed out that the definition of "Middle East" is not set in stone, and it might include the area in question. You can double check, if you don't believe me. I never came up with my own definition of it, and I definitely would not have tossed Indonesia in there.
