There's a reflexive tendency to assume that anyone implementing cruel and bigoted policies must also be stupid, regretfully, this is sometimes not the case. As you have so accurately described, it's a very careful and calculated plan to move towards a desired end state. Whether that desired end state goal looks something like Gilead in The Handmaid's Tale, and whether you're supposed to like that, or abhor it, totally other question...

Is it though? Desiring such an end state sounds pretty stupid to me.
