You are wrong here please search freely on islam and its laws and rights.Islam is a peaceful religion, you can read the history of prophet PBUH .Also you can take lectures of Dr Zakir naik in english for more information.You can read abulaala moudui book deneeyat in English for detail .
.If you can not do this, read Quran in english and tell us the points where you feels that Islam only called muslims human beings with example from Quran or hadith.Islam is polite with all human beings and respect all human beings no matter its a muslim or non muslim
read the history of muslim wars and you will find these rules ,
war will be defense , not killing womens ,innocent childrens ,old mens,ban on destroying non muslims worshipping places, ban on cutting trees and poisoning water
Islam is a religion of mercy to all people, both Muslims and non-Muslims. The Prophet was described as being a mercy in the Quran due to the message he brought for humanity:
"And We have not sent you but as a mercy to all the worlds." (Quran 21:107
Islam is a religion of tolerance. It has granted equal rights to the non-Muslims in the Islamic State, but without imposing equal duties on them. The reason is that Islamic State, unlike the modern national State, classifies citizens into two categories according to their religion or faith: Muslims and non-Muslims. Muslims have different kinds of rights and duties than those of the non-Muslims.As the Islamic State is an ideological State, its defence (jihad) is the duty of the Muslims only, while the non-Muslims are exempted from this duty.
