A lot of digital ink has been spilled over this issue.
However, some things should be pretty obvious to everybody.
1. The location was picked intentionally to be as offensive as possible to the majority of Americans. Seriously, more people are opposed to this thing percentage wise than voted against Walter Mondale.
2. They (the Cordoba folks)have every (1st Amendment protected) right to build it at that location once they have legal title to the property. That's how the 1st amendment works: The more offensive the speech the more protected it is. And do not make the mistake of thinking this is about freedom of religion. It's clearly a big "screw you" message, and thus protected speech.
3. The folks who are opposed to this thing have every (1st Amendment protected) right to protest it, short of actual violence. Oh and for you folks on the "moral relativist, all cultures and religions are equal" side of the isle, remember: The more offensive the speech the more protected it is. Works both ways.
These are not contradictory statements.
