Comment on a recent incident of domestic abuse

Recently, a Muslim man committed a 'honor killing' in upstate New York. The method chosen to dispose of his victim, his wife, was death by beheading.
A prominent Muslim cleric Imam Shaykh Hamza Yusuf has spoken out against such killings (see video here) and is rightly shining a light on domestic abuse amongst minority groups across America. I am glad. However, it irks me that he nonchalantly refers and compares to incidents of domestic abuse in Jewish and Christians families in the following words while making the case that domestic abuse is prevalent across many religious denominations:

If a Christian beats his wife up, it's not Christian violence, if a Jew beats his wife up (from what the statistics show, it does not happen very often), but if they do then it is not Jewish violence - if a Muslim should do something to his wife, suddenly it has something to do with the religion of Islam.

Dear Mr. Hamza Yusuf, there definitely is a difference between beating and beheading. I really do not remember the last time we saw the words 'domestic abuse' and 'beheading' used in the same sentence and the latter being used as a vehicle to propagate the former. Yes, speaking out against domestic abuse is a good and a much needed thing, but comparing beating and beheading are poles apart...
