My first objection is against the title here. I wonder why the word "desis" has been used here and in which context? We do not have foreigners here, do we? Or is it like ppl living abroad exclude themselves from being desis? In that case, its quite opposite for me, since in my case, it happened only once, I mean dragging the things out of one's blogs and etc, and it was done not by a desi according to your definition.
There are few foreigners here on GS for example Spanishgirl, Ohioguy and few others.
