Being a terrorist doesn't have anything to do with your religion. All religions teach peace and justice; it is up to an individual how he/she perceives that. For example, Islam tells Muslims to spread Islam in a civil way. The word, civil, in that context to some people may mean to go kill people to prove a point. To others, it may mean to be a good person to make others love you and be inspired to convert to Islam. In the end, every person is different and religion has nothing to do with who you are.
In addition to the Muslims who kill people, there are the Christian Scientists who refuse to take their children to the doctor and the child ends up dying due to medical neglect. Also Scientology won't let a person join unless the person goes off all psychiatric drugs. Religion has created wars which have killed more people then anything else in history.
I remember when America put "under God" in the pledge and "In God We Trust" on the money in order to fight Communism. Funny how using religion as a weapons works.....it doesn't! Then again, America outlawed alcohol in the Constitution for religious reasons, so who knows what American Theists might think of next to do!
No, I do not think that governments should abolish religion to defend against terrorism. First of all, it is in our Bill of Rights that an individual is entitled to freedom of religion. It should be of no concern to the government what a person's religion is.
Secondly, how could a government possibly abolish a religion? People would just practice it behind closed doors or move to locations that didn't ban practicing religion.
Lastly, abolishing religion would likely have the effect of radicalizing the followers of that religion against the government. That's exactly the kind of result the government wanted to avoid in the first place.
Religion is not the cause of terrorism, fundamentalism is. Religion in and of itself is not a bad thing, and government should not have the power to tell its citizens what they can or cannot believe. Terrorism is worth fighting, but getting rid of religion is not the way to win the fight.
Outlawing religion would just encourage even more terrorism. The answer to extremist is not to become equally extreme. That just plays directly into their hands. Freedom and liberty, as well as civil liberties, need to be maintains at all costs. The police and intelligence agencies can guard against terrorism well enough by themselves.
