I acknowledge that I misunderstood your intentions. As usually the purpose of highlighting something as being 'unjust' or 'wrong' is to imply that it should be changed. Although from your other comments the assertion that you are being highly ethnocentric and forcing your cultural values and norms onto an unrelated culture still stands. It is of extreme importance when looking at a cultural trait to look at it in its own historical and cultural context.

I am not seeing how this example could work. As this is a case of a people having standards from a different culture enforced upon them. As opposed to people having the values and norms from their own culture. There is a world of difference between one ethnic/cultural group dictating what another ethnic/cultural group does and people following their own culture.
