I understand your point and I'm not denying that there are Muslims who do these horrible things, but here's my rebuttal since there's plenty of us who are also discouraging or not even doing such actions:
1. Child rape happens in the poorest of Middle Eastern nation and is also a byproduct of Arab tribalism.
2. Exploding innocents is actually forbidden. We're only supposed to fight NonMuslims if they instigate the situation and/or break a treaty.
3. Genital mutilation: see 1
4. Mass Murder: see 2
5. Keeping a dog as a pet is only forbidden by Salafi jurists. I've owned dogs and know plenty of Muslim folks like me who own them too, we just aren't allowed to keep them indoors.
6. Women where I come from especially have the right to wear whatever they want, whether Hijab or even jeans and a tanktop. The Hijab has existed since even in Pre-Islamic Arabia.
7. Pouring acid on women's faces happens only in Pakistan/South Asia and nowhere else in the world.
The practice of Bacha Bazi exists only in Afghanistan and is not because of Islam, but of Afghan tribal culture.

In fact, the Mujahideen outlawed Bacha Bazi, the spread of Opium and Soviet settlement and were doing well before a splinter group we all know as the Taliban came to existence.
