It does not happen in my community.
The reason you're being asked is because those asking you are flat out bigots, guilty of essentialising Islam.
When Amanda Hutton was convicted of the manslaughter of her child last week, the response on MN was not "Why don't white people know more about this?" Long before Hutton is viewed as "white", she's viewed as "an alcoholic", "a DV victim", "having PND" or, indeed, "a killer of children". No-one attempts to argue that we can learn from her case anything about what it is to be a white woman today, and no-one starts implying some sort of Test Act which says that there is one true response to the story, and anyone who thinks otherwise is a secret abuser. Oh, OK, the last: people who attempt to contextualise it will always clash with people who just see it has unmediated evil, but I don't think that each side in that conflict thinks the other has a chamber of horrors in their bedroom.
But when there's a story about Muslim family dynamics, it's immediately about Muslims. The most extreme cases (Shafelia Ahmed, say) are used as sticks to beat the entire Muslim community (or, more to the point, all the disparate Muslim communities, plural) as though every Muslim mother secretly wants to marry her child off in Pakistan or kill her in the process. Rather than it being seen as a case as far off the scale as the Amanda Hutton case, it's seen as somehow a metaphor, or something more concrete, for "how Muslims live today".
There are, of course, people who are nominally Muslim who also abuse their children. That's true in every community. Fred West had neighbours and friends, too. The gross racist libel comes when in the aftermath of accounts of abuse, the implication is made that "they" are all up to it really, and that the utterly abhorrent attitudes towards children, women or whatever the topic is are widely shared and implemented amongst "them".
Sure, as Crescentmoon outlines, lots of people would like their children and their grandchildren to follow their values. But to take from that the idea that they would enforce those values through abuse is crazy. There are, of course, people who do enforce them, who are crazy. But they are no more common, no more accepted and no more excused amongst the Muslim community than anywhere else.
