That was a response to Knoxcollege that NO religion JUSTIFIES violence

Just a few examples where violence is justified in religious texts:

The Quran:

"The punishment of those who wage war against God and His Messenger, and strive with might and main for mischief through the land is: execution, or crucifixion, or cutting off of hands and feet from opposite sides, or exile from the land: that is their disgrace in this world, and a heavy punishment is theirs in the Hereafter;" (Sura Al Ma idah 5:33).

"Fighting is prescribed for you, and ye dislike it. But it is possible that ye dislike a thing which is good for you, and that ye love a thing which is bad for you. But Allah knoweth, and ye know not." (Sura AL-BAQARA 2:16) The Quran

I shall cast terror into the hearts of the infidels. Strike off their heads, maim them in every limb. Q. 8:12

From the bible:

"As soon as Jehu had finished sacrificing the burnt offering, he commanded his guards and officers, "Go in and kill all of them. Don't let a single one escape!" So they killed them all with their swords, and the guards and officers dragged their bodies outside. Then Jehu's men went into the fortress of the temple of Baal. They dragged out the sacred pillar used in the worship of Baal and destroyed it. They broke down the sacred pillar of Baal and wrecked the temple of Baal, converting it into a public toilet. That is what it is used for to this day." 2 Kings 10:18-27 NLT

"Happy those who seize your children and smash them against a rock." Psalms 137:9 NAB

In that day those the LORD has slaughtered will fill the earth from one end to the other. No one will mourn for them or gather up their bodies to bury them. They will be scattered like dung on the ground. (Jeremiah 25:33 NLT)

I don't go to mythical places with strange men.
