I know that other religions were violent too in the past but today in modern age it seems that Islam is the only big religion that has a lot of people who are willing to spread their religion by violence.
I’m sorry in advance if anyone got offended by this question. I respect all religions, I’m just interested in the background.
EDIT: Thanks everybody for answers. I didnt expect this “controversial” question to have so many upvotes. I expected it to be downvoted to hell.
While some of you guys tried to advocate Islam extremists by comapring them to KKK or Crusaders (I already said in post that I know other religions were violent too – please read the little text under title) or doing conspiracies about how media made muslims a general dummy, others made quite complex answers that actually explained the background of this situation.
