Constructing a memetically safe space is ... dangerous.

Sure. It's just as well no one is proposing to do that.

The situation here is as follows. The OP is really bad, for several different reasons. Nancy made a comment that rather vaguely suggested that she might invoke her moderatorial powers somehow if the author didn't justify some of what he wrote. But now you're pointing to one of the things I say is bad about the OP and saying "it would be bad to ban people for just this". Yup, it would, but no one was suggesting that.
