The answer is a resounding YES! Isn't the belief in religious freedom one of the great things that make us unique as a country?
However, religious freedom in practice is now and always will be tenuous at best. We live in a time that could enable those who seek to harm our country to use religious freedom as a springboard for doing so.
It is difficult for most westerners (myself included) to differentiate between a Muslim extremist and a moderate Muslim. One thing is true however, and that is that the individuals who perpetrated the attacks of 9-11 were Muslims. In fact, Muslim men have comitted many attacks/atrocities against those who hold other beliefs around the world over the last 40 or 50 years. That doesn't make them all terrorists, but how are we to tell the difference?
If there is a conspiracy between the so-called moderate and extermist Muslims to harm America, what better way than to implement the modrate branch of Islam as "bridge of peace", while funding the extremist through back door channels. Granted, it's probably paranoid, but rhetorically, wasn't that what folks were saying about Hitlers plan for attempting a world takeover when German troops crossed into France?
Do the Muslims have a right to build near "ground zero"? Sure they do, but that doesn't make it tasteful. If the true intention is to build a bridge of peace and healing, then why not use funds from the moderate American Muslim community actually build a small bridge over perpetual stream near ground zero honoring those who died there. Just an idea, but I think that more folks would see that as a true "olive branch" for healing.
By all means build the Mosque; enjoy the freedom granted all Americans under the Constitution, but please do it away from ground zero if the true intention is to promote emotional healing.
