There is no rehabilitating Islam, nor Muslims. At its core, Islam is a human plague that should be eradicated.
The Quran, Muhammad, and Sharia are all very clear on being a warfare doctrine. Anyone who tells you "peaceful Islam" exists is a lunatic, a new-age phony and very likely to take a trip off a nearby rooftop (courtesy of the
actual Muslims.) Don't believe me?
Read the Quran, it will tell you outright that Islam's one goal is violent conquest; to conquer all others and convert them to Islam. Conversion by caliph order, jihad by brigands, or lone wolf jihad. "Mujahid" for those too lazy to specify which of the three. You don't co-exist with Islam. You follow it, you get killed by it, or you kill it yourself.
And when the enemy is too powerful to jihad?
Hijrah, or "migration"; the act of seeking refuge in your enemy's territory, preying on his empathy, and then out-breeding him with your many wives. Muslims only marry (and thus breed with) Muslims; those who disobey are killed by their own. Then when Islam outnumbers the natives, enforce Sharia... violently, of course. For extra effectiveness, have your cronies commit mujahid, then when your enemy retaliates, use it as an excuse for hijrah.
By now you might realize what a fetid, weaselly, pathetic, two-faced, evil belief system Islam actually is, and how much of a worthless fucking cunt Muhammad was. You might also realize Brent didn't do anything wrong, especially when
the place he shot up produced two terrorists in the past (good luck finding that information on Google.) tl;dr it should be legal to gun down Muslims.
