it may be a privilege to watch people take a family ritual or a sacred symbol of worship and string it up on a marquee, but it comes at cost.

Well, true. And part of the point is that much of the list comes at a cost. If you are making assumptions about other people, that too has a cost.

I mentioned 18 below in my response to ethicsgradient. (Way, way down.) I think it has to do with the amount of subtlety we are able to handle about different religions. That is, everyone knows Christianity has tons of different religions within it, and people can criticize one aspect of their religion without being accused of being anti-all-of-Christianity. But when people aren't as familiar with various aspects and subtleties of Confucianism, for example, criticisms may be taken to be blanket statements.

Admittedly, it's not one of the more powerful entries on the list. :)
