OK, I just looked at the next five or so objections that that website has to the Quran, they seemed minor. Then came 3:149-152 "O you who believe! If you obey those who disbelieve, they will turn you back on your heels, and you end up losers. Allah is your Master, and He is the Best of Helpers. We will throw terror into the hearts of those who disbelieve, because they attribute to Allah partners for which He revealed no sanction. Their lodging is the Fire. Miserable is the lodging of the evildoers."
I think it's easy to see how that (the "WE") in concert with the other quotes could be used as a call to attack disbelievers and non-Muslims.
