the quran has so many verses regarding nonmuslims or nonbelievers
there was a muslim in a forum called 'allah is the greatest" where he was using this line from the quran when talking ill about nonmuslims and their role in afghanistan:
Qur’an (9:73) - *“O Prophet! strive hard against the unbelievers and the hypocrites and be unyielding to them; and their abode is hell, and evil is the destination.” *
he was just prejudiced but he also was ignorant of the context of this verse. unfortunately some muslims take these verses out of context and give islam a bad name.
this verse is only related to a situation with the Holy prophet where a few nonmuslims were trying to attack him, that is where this line comes from
I don't really know about this verse, but I found some verses to counter the stupid theory that Islam allows senseless violence against Non-Muslims

“Say, ‘The truth is from your Lord’: Let him who will believe, and let him who will, reject (it):……(The Noble Quran, 18:29)“
