Only thing is, whatever you said is false. Historians have studied the spread of Islam and issue of forced conversions----and that just wasn't the primary vehicle of Islamic spread. Nobody is apologetic, we just laugh at you for trying to pass 'forced conversions' bs when
all historians, non-Muslim Indian and Western alike, agree that Islam wasn't spread in Iran/Egypt or even India by "forced conversions"
Here, some education for you.
