History is full of twists and turns towards 20th century climax and 21st century ultimate. So never blame history and do have right character and good quality to whichever religion or nation or nativity one may belong. Islamic invaders converted Hindus in India because Hindus then and there were either lacking right character or good quality. Nobody or no ruler changes other/s for nothing as there is no need to change so. Conversion is because of lack of either right character and/or good quality. Present Indian constitution and paksitan constitution can't help against past conversions. My point is that one has to be human(right character and good quality) by becoming at first than worrying about his/her religion and conversion. Physical existence is different from its mind(law)(religion). And believing in mind is crime in social. One should believe in sense(heart)(human) first by respecting mind(religion)(law). Righteousness against other righteousness argument must be through path another righteousness path towards prevailance of self-righteousness and self-elimination of adversaries to self-righteousness by themselves.
