Dear Chris Goh,
Before you start accusing people. Please learn more on Muslim rules and ethnic rules.
Most of the events happen are rule by ETHNIC rules not religion.
Therefore, before you start accusing other people religion please check whether your statement falls under which law
1. Human made Law
2. Ethinc / Group Law
3. Religion Law
4. Country / State Law
As you claim "Haven't you heard about the brothers/fathers killed their own sisters/daughters" this is NOT under any ISLAMIC LAW. This is more towards certain ethnic group in some country.
About the 9 years old marriage. Please read more on this issue rather than follow the voices. Start reading more on Islam foundation before accusing other people.

By the way, when westners read about Islam, they tend to make Islam into westeners customs which they will be very bias.
Learn and understand other people position, custom, religion. Not all people can be Asian or Arab and not all people can be westeners.
There are a lot of discussion on this matter, so read on BOTH side of arguement rather than one side.
Thank you,
