jews and christians are also supposed to kill those who dont follow their beliefs.
To be honest, they're not supposed to do that today.
The quran, however, tells you to force your religion on nonbelievers, even through violence.
Basically, it seems that Islam is leaning towards force-based conquest, whereas the other is leaning more towards "let-them-choose-for-themselves"-based conquest.
TBH I kinda wish there wasn't religion.
