so in your opinion it sends no message to muslim extremists to build a mosque on the site of a terrorist attack? i
There's a difference between sending a message and getting one.
If some terrorist camp over there thinks that the building of that mosque has some historical significance as a marker for their success, it makes no difference. That is, they aren't terrorists because that gets built. And, that they take some perverse delight in it is really of no consequence other than that it bothers some people here -- even though it makes no difference in practical reality.
On the other hand, if the mosque is viewed as a place or a cause that forces us to confront the lack of mutual understanding and respect then there is at least a chance that somewhere down the line it, and places like it, will allow generations of both Muslims and American to decide that their antagonism is something ginned up by people who want to take advantage of it.
Osama Bin Laden is a politician. He uses Islam to further a political agenda, and sadly he and others like him have had some success. The ultimate way to combat that -- assuming we cannot kill all of them and that has never worked -- is to beat him at his own game.
On the flip side, people like Gingrich, Limbaugh, and Hannity are entertainers who are trying to make a buck off of the tension and dispute. They are opportunists, just like Bin Laden.
Until people learn to think for themselves and don't get caught up in all the nonsense, we will always have these problems. Best way to handle it, even if you don't like it, is to not let it bother you.
Honestly, day to day, what difference does it make that there is a mosque two blocks away from Ground Zero? Me, I'd rather work to prevent another one than bash people over the head claiming that ten years after the fact a mosque a couple of block away is such an affront.
