according to who, you? you sound like those who say the minarets are a symbol of Islamic glory and an insult to Europe or whatever crap they like to come up with.
perhaps it's an attempt to remind people of different religions of "La Convivencia" that once upon a time existed in Al-Andalus? why must you assume the worst of those people who have stated that the whole purpose of this Islamic center is to show the real face of their religion as opposed to the face that showed up in Ground Zero 9 years ago?
while that argument does make sense to some extent, i still don't get why it's so hard to understand lots of americans' feelings regarding this issue. after all, it was muslims who (allegedly) came to america nine years ago and murdered in the name of allah - yet the burden is on the victims' families, their widows and children, to exhibit tolerance for muslim insensitivity. pretty weird.
btw even turks i talk to over here (who are fairly moderate compared to syrian or iraqi muslim immigrants) recognize cordoba as a symbol of islamic conquest. muslims built the al-aqsa mosque on top of the jews' revered temple mount in jerusalem, transformed the st. sophia basilica in constantinople into a sprawling mosque complex etc., so it's not like there's no pattern.
