Islam. Is it a "religion for peace"? Do we understand it? Have we treated it unfairly? (With prejudice and discrimination?)
Considering recent events like "Woolwich" (http://www.bbc.co.uk/news/uk-22664835) I can imagine many feel that Islam isn't a religion for peace.
However I would implore you to watch those TED talks linked in the description (especially "Lesley Hazleton: On reading the Koran" and "Bobby Ghosh: Why global jihad is losing") to get a better perspective on Islamic culture, and its true teachings (of peace and compassion).
All of these TED talks clearly indicate that Al-Qaeda (and other organizations) have distorted the true message of the Quran (or Koran), for instance in the Quran (or Koran) it never mentions "72 virgins".
It is interesting to note that Al-Qaeda's motives seem more political than religious. And their method of recruiting people (http://220.127.116.11/content/dam/rand/pubs/reprints/2006/RAND_RP1214.pdf) where they seem to use various psychological mechanisms (like "conformity", "obedience", "dehumanization", and imbue a "conflict of interest") to make their cause seem more reasonable. This is quite vividly seen in the TED talk "Sharmeen Obaid-Chinoy: Inside a school for suicide bombers" in the description.
However Philip Zimbardo (if I remember correctly) in his Book "The Lucifer Effect" argues that many of the suicide bombers were of middle class, or high class origin. So nobody is immune.
Before I say any-more I strongly recommend everybody (at least) watchs this short (3 minute video) : "On Iran, Islam, and Amazingly Stupid Comments"
Now my last part :
Do we treat Islam unfairly?
Have our nations (the west) genially incited hatred towards us by our exploitation f their nations. (If this, of-course, is true!).
Considering (on another note) that most Islamic people are just normal nice people. Like me or you! :D
