Guess you've given up on the risible notion that you know more about the design of a memorial than the artist himself; smart move.
No, I haven't given up. I still don't think it's a crescent. I know what a crescent is. (Among other things, in some heraldic systems it is the emblem of the second son.) And I still think the argument (not its proponents) on your side is ridiculous and paranoid. I suppose it is good to make the architect aware of a possible interpretation of an unintended and inadvertent aspect of his design.
The character of the response to the statement of a dissenting view suggests to me that there something going on here of which I am not aware. I, personally, am not worried about crypto fifth column Islamofacist sympathizers tricking me or the nation into paying homage to the perverted heresiarch. I am suspicious of arguments which need their proponents to imply that they are just so much more on the ball and so much wiser even than the bereft who have a strong personal connection with the memorial that those who disagree with them can only be vicious or stupid.
I guess contempt for those who disagree with one is not confined to Islamofascists.
