Well, I think that it's all a bunch of poppycock. Islam, Allah, Christianity, religion in general.
But I can't think of anything more offensive than a mosque being built anywhere NEAR the ashes of the Twin Towers. The very thought of it makes my blood boil. I am certain it will be regarded in the muslim world as the ultimate victory much like they have done in the past putting their mosques atop of their conquests and areas forever to be claimed Muslim. It would be like sticking a golden dagger in the corpse of every infidel that died in their glorious victory. It will be to them, like it was for us, the day our astronauts planted a flag into the moon.
If this is allowed, I will not only condone, but applaud any steps taken, vigilante, or otherwise, made to bring that mosque down. I hope our leaders know that we are watching and taking names. Washington is already on the wrong side of the people in their refusal to enforce immigration laws. This will be the straw that broke the camel's back to a LOT of people who remember 9/11. I hope they make the wise decision.
