Religion and Terrorism

Lately I have been noticing that the general public has affiliated terrorists groups with specific religions. Now this is not a biased opinion, however ever since 9/11 has occurred the United States has gone to extreme measures of screening every single Muslim person in their country. Whenever a person with the name Mohammed, Abdul, or any other Islamic name tries to go for a vacation, they are screened before they can fly. I think this is discrimination, and just because the individuals that are with the Al-qaeda are Muslims does not give the public an excuse to cast them by their religion. Not all Muslims are members of Al-qaeda, and not all Muslims are bad. There are many races that have terrorist groups such as, FARC (Revolutionary Armed Forces of Columbia), KKK, and Tamil Tigers, so what makes them different from Al-qaeda? There has been so much media frenzy about Al-qaeda that it has literally hypnotized the world into believing that Al-qaeda is the worst terrorist group in the world,but in reality it is just a newly born group that has gained stardom in the recent years. What i'm trying to say is that we shouldn't discriminate people just because a certain terrorist group is from their ethnicity, and to religiously discriminate them is, by far, human ignorance.
