However we will defeat them all and achieve our eventual victory! There will be struggle. There will also be victory. Katzensieg Heil! We will march from victory to victory!
tukabel admits that all belief systems are essentially religions, with core premises that require faith to believe, tenets, prophets, and clergy.
Indeed tukabel's own "Rationalist" ideology is just that: a religion. Can tukabel prove that a civilization of highly "rational" AIs is the best form of civilization? His premises are no less toothless as those used to justify the existence of God.
Rationalism isn't really a belief system. Instead a true rationalist should update his/her beliefs including metaphysical ones based on new evidence. Hence if there is enough evidence to support theism then a rationalist must recognize the existence of a theistic deity.
