I am a Muslim. I know the reality. There is nothing wrong there (Muslim community) and nothing of this type - as it is made out/like how you are feeling reading this article. Cool....
It is just an isolated case. You will know about it, may be, if you cross-check with educated-class muslim families or may be if somebody conducts a national or city-wise survey on this subject and covers educated-class muslim families.
Yes, certainly, with one odd such case, we cannot question or begin to think as "whats going on in muslim community".
Trust this clarifies your question and helps you find the true reality.
