The author of this piece doesn't seem to know very much about Islam. In fact, the sura which speaks of "no compulsion in religion" comes from the earlier Meccan period, while the most stringent calls for jihad against non-Muslims are in the latest suras of the Medinan period toward the end of Muhammad's life. Islamic exegesis employs the doctrine of nasikh, or abrogation, which means that an earlier verse is cancelled by a later verse, when there is a contradiction.
