The problem is that we south asians are a highly biased nation because we think on ethnic lines and not merit. People have been voting on regional basis not because of girl/boy issue. Among girls, Regionally Deepali is getting votes from Bihar and Ankita from UP but the begal market is crowded so Puja is having problems because better singes like emon, amit and prashant are from the same region. Parleen is the only solid candidate of north india so he probably gets votes from all over north india. Abhishek is from bangalore where II is not followed much.
I have noticed many pakistanis on this forum linking parleen. Also most pakistanis are punjabis so they seem to favor parleen irrespective of his talent because parleen is a punjabi. Regional bias is everywhere.
