I like to read international perspectives of hot topics in the U.S. The issue of memorialization and remembrance of loved ones who die in war or by other tragic means (like 9/11) is almost always controversial. And religion complicates matters. In my opinion, what would be a tragedy is not if this mosque is built, but if some Christian extremists destroyed it, and killed innocent people in the process.
I also find the debate about President Obama's religion puzzling. Who cares if he's a Muslim or a Christian...or nothing so long as he has some sort of moral compass?
