In fact waging wars clearly means Islam is not a peaceful religion. The act to dominate the world also clearly means Islam is not a peaceful religion. The same goes to Islam expansion and the jihad to achieve this, either you breed to expand or you wage war and dominate to expand, and from your post it is is likely to be both.
1. Not every Muslim is an extremist. In fact most Muslims we never see them going out to bomb others. There are black sheep in every grouping, why people take the minority as the representation of Islam ?
2. Even Christian apologist David Wood admits that Christianity was once upon a time not a religion of peace. And even in Buddhism we find certain monks had performed violence. Perhaps there is very little meaning to obtaining a recognition as a religion of peace ? Why people seem to be a lot more critical about Islam ?
3. Islam followers are taught the idea of retaliation when needed. When a violent act is performed by a Muslim, with a little mental acrobatics, it can be passed off as a form of justifiable retaliation or even a self defence. And hence for example, anybody who leaves Islam can be perceived as trying to sabotage Islam. And hence it becomes justifiable to kill the apostates. And hence the 911 and paris terrorist attacks could all be passed of to fit the teaching of Islam. Is it reasonable to expect people to just receive oppression without doing anything ?
The assertion that "Islam is not a religion of peace" will probably require further elaboration.
What exactly people mean when they say Islam is not a religion of peace ?
