Well, reading this you might think "how can that compare to raping boys? Boys are human beings and human beings have rights, just like you and me? But at the same time a Muslim may consider refusing to eat pork a law by god which is way higher than anything considering humans.
The point I try to make is this: In an intercultural environment you need to accept the other one doing things you consider immoral. Otherwise there will be no cooperation at all. You must not judge. We all know that and when we talk about it we think about clothes, how to say hello, and kinds of food. But if you really want to achieve important cooperation you also need to consider points like this. That's the tough part, accepting these things that are really undiscussable in your culture. In an intercultural environment they should be.
Now please, don't just downvote. Write a comment. Thanks.
