have you counted the number of churches within blocks of each other all over the country? what difference does it make if there is a mosque a few blocks away? maybe they'll combine, maybe the other mosque is too full...your POINT?
mosques are not community centers. this IS a community center with a provided area for worship. here's the theory. people go to the community center to swim, take a class, eat...and here it comes...are you ready? PRAY. so, they...wait for it...here it comes...provide a clean, quiet area for them to PRAY and return to their activities. wow, sounds scary to me!
oh, and let's not forget that pesky First Amendment Freedom of Religion that says they don't need your approval.
