If people are attacked for marrying someone their family doesn't approve of, yes. The modernising bit I meant is the modernising of ideas, such as allowing adults the freedom to make their own decisions based on what they decide for themselves is important to them, and not be dictated to by rules which may have had a sound basis in certain circumstances once upon a time, but which are no longer relevant. In short, yes, modernise out of class prejudice (or any other prejudice for that matter).
Yes, we need to improve too, but we in the 'west' (mostly) have improved in respect of what the article I referred to is talking about.
Or haven't we?
