They don't "reattack" the norms they introduced, they seek to represent both camps for more control. Maybe to have a sort of an "alibi" too, if things turn ugly.Ultimately for context, the Semitic spirit attacks whatever is the mainstream norm. Or putting it another way, whatever the norms are for Whites. But because Semitic attacks work, and because Whites on the whole are open to new ideas, their attacks at some point often become the norm for Whites, which they then reattack as the generations shift and new humans are born.
