This question already has an answer here:
Does the Koran give permission to kill Non-Muslims? Since I read so many reports of Muslims pressuring Christians to take down Christmas trees, destroying Buddhist monuments, Western cultural artifacts it seems that Islam will not tolerate anything that is not Islam. I read that many Non-Muslims are dying (being killed) because they will not give up faith in God that Muslims perceive as wrong. I wonder how the future of humanity will be if Muslims attack Non-Muslims. Where do aggressive Muslims get the right to attack Non-Muslims? Does this permission really exist within the Koran?
