first of all religions represent peace (Islam/Christianity/Judaism/and others) but there is always the blood-thirsty people and we don't find that in Islam only, if we go back to history there are the crusaders who slathered thousands and thousands of Muslims before, and the examples are many to be listed (no offend to Christians).
So the problem comes with the ways of the Americans and the western people,in america it is mentally okay to smoke weed,drink alcohol,have sex(which is actually bad),Muslims have a strict rules/guides to make people free from the addiction of lust(for the Americans/western people they have no lust control)
example: Ramadan:a holy month when Muslims fast from the break of dawn until the sunset(no food/no water/no sex) a video that shows the difference in English here
but in the qaida and isis prolem we find that these people has nothing comong with the religion islam
example:
jihad a niqah: (for the isis) a women have to offer her body (sexually) to a solder or mujahid
and here again we find the problem of the media publishing nonsense and that doesn't include just Muslims/Arabes but also Australians and Americans themselves
example:
americans/'MURICANs: people of the racism land and democracy(feel the sarcasm here),white fat kids with nothing as a brain(no offense)
so the problem here is that a bunch of people killing innocents in the name of Islam and God. note:i like to write in huge letters
