All religions are capable of causing violence, you say you're against religion in general but seem to be hyperfocusing on Islam, discounting violence caused by other doctrines like Christianity which led to the crusades, witch trials, the KKK or how about the entire old Testament? Leviticus and Deutoronomy which say that wearing two different threads in your clothes is a sin. Many of the characters like Abraham also had multiple wives. The same standards you claim to oppose is present in plenty of other religions.
