GZ shrine Muslims should build

We have been repeatedly and forcefully instructed to believe that, when the Left expounds the Muslims' right to build a mosque near Ground Zero, it's only about religious freedom. Those who want to build that mosque really don't seek to offend Americans nor to hurt the families of the thousands whom their Muslim brethren murdered there only nine years ago. It's only about religious freedom, see. Okay, then I have a suggestion. To demonstrate their dedication to religious freedom, perhaps those mosque-builders could instead erect a non-denominational shrine where worshippers of all religions could celebrate their faith Muslims, Jews, Christians, Unitarian/Universalists, Buddhists, Hindus, Jains, Sikhs, Taoists, Animists, Nihilists (do Nihilists celebrate?), everyone.

How about it, guys? What could more wholeheartedly reflect your fervor for religious freedom? Show us.
