Let us say this case is true. So, that means if one case like that happened among +1000, 000,000 Muslims it becomes as traditional thing on their lives..?!!
I think any mature person with good education can understand that for every rule there is exception!
Religion is not judged that way, and for those who say Islam is the religion of terrorist I just would like to ask them one question,
If you are living a happy life with your family in your peaceful country and some outsiders came and kill all of your family, your father, mother, old & young sisters and brothers in front of your eyes in a very aggressive way, So, if you give your soul to revenge for them means you are terrorist..?!!
Well, I can understand that your brains have been washed in your early ages and all of the wrong information about Islam has been fed in your creating that blind hate to that religion.
I wish the day of the truth comes soon. 
sir, you allowing your own innate bias on this subject to make you sound obtuse
your acting like the marrying-off of very young girls is some anomalous phenomena; when it is surely NOT....a cursory google search will reveal dozens of articles detailing the plight of these young girls.
sure, most muslims in the west do not do it....only cause they are not allowed. if sheria law were in placde in the UK, like its muslim population wants.....thsi would certainly be going on
and in countries like jordan, saudi arabia, and pakistan.....this is a VERY VERY common occurance
its one major facet to your religion....at least own it
