Yes, welcome to the forum Seand.
Re: Your question, I think the possible culprit is the bible itself. It is a text that's old testament is replete with god's ordinance of intolerance and death, or rape and conversion, of tribes not in keeping with "his" (gods) law!
Consequently faithful texts like that which you mention are said to be tools of the infidels or the work of the devil. And those that question the ordinance of god's word are to this day, said to be deluded of the truth. (Even here through out various threads, if you read well enough.) It's a certain insurance of one's faithful institutions avoiding extinction, to claim all others are the enemy and sanctioned for; death or assimilation. (I'm getting this cube picture and "Borg"...

) And because of this faithful edict against all others not as one's self (faith), one contrives a market of conquest and dominion, which is affective today in decimating cultures and corrupting ancient tribal memories as the "old ways" are strictly forbidden or governed by the new faith that invades indigenous peoples.
Whether it's Islam in the Mid-E, or the rain Forrest tribes that are losing their native tongue because it is forbidden under the dominion of the religious missionaries that follow any countries cultural alteration under the auspices of government occupation.
Why? Because they are commanded under god's word to convert the unbelievers! Read the bible and read the history of absurdly titled; "holy wars", like the inquisition, crusades and even the American Civil War accounts and it is clear. The commandment of god above all else, is convert or die! Which is not surprise, considering he created the people and inspired the faith, and damns for eternity those who don't believe!
