Followers of Islam are Muslim, Muslims are Islamic, what is the distinction you are making? I guess you are saying to be against the religion versus the followers of the religion.
Either way though, Islam doesn’t have to be violent, people use writings from centuries ago to justify violence that would be there without their religion. Islam like Christianity and essentially all major religions preach peace and love for all people, even your enemies. They require doing good service like giving to charity to obtain salvation. Islamic groups have lived peacefully alongside other religious groups countless times.
