So let&#x27;s quantify your definitions of &quot;significant&quot; and &quot;terrorism&quot;. In the past 5 years, about 2% of terrorist attacks in Europe were found to be religiously motivated [0]. The majority are perpetrated by separatist organizations.<p>There are over 1.6 billion Muslims worldwide [1]. Size estimates for the terrorist groups are: ISIS (52k - 258k [2]), Al Qaeda (19k-27k [3]). There are others, but I believe these are the main ones that people are talking about when worrying about terrorist threats abroad. We&#x27;re talking about 1 in 5,600 to 22,535.<p>My humble opinion is that the terrorist threat worldwide is indeed significant, but if you think that it is a problem with Islam, then you are playing right into the hands of the extremists, who want (and they have publicly published these intentions) to divide the world into two camps that hate each other. The more hatred you direct towards Muslims, the more you drive them apart from you. ISIS&#x27;s stated objective is basically world war - they <i>want</i> you to hate Muslims, so that Muslims feel like they have nowhere to go in the Western world.<p>[0] <a href="http:&#x2F;&#x2F;thinkprogress.org&#x2F;world&#x2F;2015&#x2F;01&#x2F;08&#x2F;3609796&#x2F;islamist-terrorism-europe&#x2F;" rel="nofollow">http:&#x2F;&#x2F;thinkprogress.org&#x2F;world&#x2F;2015&#x2F;01&#x2F;08&#x2F;3609796&#x2F;islamist-t...</a>
