The Internet really has a lot of opinions and these opinions allow you to make your choice. For me Islam is an aggressive religion and I don't care what you think of this site. Proof that what the terrorists shout Allahu Akbar.
Most of the major religion-based terror organizations (such as the ISIS and the Al Qaeda) take inspiration from the Islamic teachings. There may be a few terror organizations based on Christianity, Buddhism.etc., but they are less than 1% of the total.
