Dear sarbakaf, have you not heard of mirza sb and do you think he was alone? If you are one of those who think no one converts from muslims to other faiths then please take of your blindfold.
People have been changing religions always. The quran tells us about ulema of bani israel. Most people whom the quran calls fukaar went into kufar from islam. Son of Noah, wife of Lot. So please spare me from petty arguments.
If you must please go to youtube and watch christian videos. It is the truth based on evidence that matters not what you claim to believe. Make beliefs don't stick when push comes to shove.
regards and all the best.
