Is that the best you can do? ;P
Islam is a vengeful and bloodthirsty religion (like most other religions)
You get your arm amputated for thieving making islam brutal, barbaric and stupid. If somebody was poor enough to steal by amputating their arm you are not going to improve the situation.
You get buried to your waist while your family and other locals throw stones at you, if you have pre-martial sex making islam brutal and barbaric.
You get hanged for blasphemy which is stupid.
You get hanged for apostasy (leaving islam), which contradicts the idea of free will, making islam hypocritical.
Women are treated as second class citizens making islam a sexist religion.
