You are clueless about Islam. Please read the freaking Quran and the Hadiths there you have all the info you need, this religion is extremist by it’s own nature. You seem stuck in the something something racism, Islam is not a race by the way, it is another flavor of far right but on steroids, which happened to be enemies of the Christian far right, but the enemy of our enemy is not our friend. How the left is defending this particular religion is crazy.

How people speak about this like this is normal and ok is beyond me, but anyway, the influence is there, the belief that this is so immoral that is punishable by death it is there too. And the fact that nowadays this practice is so extended in this particular religion is another thing.

Of course the authorities of any country that is not a hell hole won’t do anything about it even if they had these “four male adult witnesses”, especially in any European countries, that might be a reason why the families do this on their own influenced by these barbaric beliefs.

Yes, there is a relation between honour killings and Islam, please read the link above. Unlawful sex relations (something that the girl did by the eyes of Islam just by having a boyfriend) are expected to be punishable by death, the only thing is that it is expected to be done by authorities.

Please also read the exmuslim sub on Reddit to see that this is not an isolated case, things like this happens all the time. Watering down Islam enables this things to continue.

If you want to know about Islam read the Quran and the Hadiths (the only real source), not some articles trying to make this cult beautiful and peaceful. It is not.
