What to do if the Mosque at Ground Zero is Built

A COMMENT on the article, A mosque by any other name: Ground Zero mega-mosque group ditches name redolent of Islamic supremacism, said this:

In the unfortunate event this mosque project goes through, since Imam Rauf claims to want interfaith dialogue, perhaps non-Muslims should pour into this place daily to the point of outnumbering the adherents to Sharia.

If he wants interfaith dialogue, then Christians, Jews, Hindus, Buddhists, etc. should all expect the same benefits and privileges as anyone else who enters the dwelling, and should practice their respective religion while inside it.

If Rauf is what he says he is, he should have no problem with that, right? Play for keeps.
