Islam gives you every opportunity it can to make you into a sexist, misogynist, intollerant, racist, supremacist, psychopath, with murderous tendencies. That's the reason this bothers me more.
In my experience, tho, that's not exclusive to Islam. There are plenty of similar passages in Jewish and Christian texts; in some cases, those texts are even worse. I mean, at least it is universally or nearly universally true in the Muslim texts that non-combatants, women, and children (although what constitutes a child or non-combatant may change) should not be killed in war. But in the "early" Jewish texts, the books of the Torah, Joshua, and Judges, killing non-combatants isn't only encouraged, it's mandatory. The reason given for King Saul's dynasty collapsing is that he failed to kill non-combatants in war. Other people were killed for the same "offense". In a lot of cases, all the inhabitants of a city that breathe, whether or not they're even human, and whether they are born or unborn, are ordered slaughtered. In some cases, some were spared--but these were only virgin girls, to be slaves (and all female slaves were automatically sex slaves). And then there's crap like Psalm 137:9: "Happy shall he be, that taketh and dasheth thy little ones against the rock."
And as for sexist? Fuck, have you READ Song of Songs (shir hashirim--also called Song of Solomon). Apparently, when women are in love, they say stuff like "1:13 My beloved is unto me as a bag of myrrh, that lieth betwixt my breasts. 1:14 My beloved is unto me as a cluster of henna in the vineyards of En-gedi." And when men are in love? This couch we fuck on is comfortable, and you're ok to look at! (1:16) The jewelry you're wearing is pretty! "1:10 Thy cheeks are comely with circlets, thy neck with beads. 11 We will make thee circlets of gold with studs of silver." (also, 7:2 and 4:2-3) Who is this woman who talked for the last two chapters about how much she loves me after I slept with her on that comfortable couch? Ah, who cares, she smells good! "3:6 Who is this that cometh up out of the wilderness like pillars of smoke, perfumed with myrrh and frankincense, with all powders of the merchant?" (also 4:6, 10-11, 13-15.) Now I'm going to go on for the next three verses comparing myself to a pillar! or wood! or a wood pillar! (dick metaphor much?) Also, I'm king, I'll fuck all the girls!
Yeah. So there's that.
