Could you clarify what your point is and why you're making it?
Although C S Lewis opposed X on the grounds that it's tyrannical, he himself would have been tyrannical given the chance
Yes. He believes that arbitrary things are bad. Belief that arbitrary things are bad would lead to tyranny unless we get very lucky and he happens, by chance, not to think any of them are bad enough to ban. Of course, he wouldn't think of it as tyranny, he'd think of it as "not allowing people the freedom to hurt others" or some such.
Almost everyone has some things they would prefer to be illegal
But religion has a habit of tossing weird things into the mix that nobody would ever believe otherwise. Do you honestly think that many people would believe that killing a zygote is murder without the influence of religion? Or believe in 7 literal day creation? People whose religion is similar to Lewis believe those things, and it's pure chance that Lewis's branch doesn't (at least for creation, Lewis didn't say much about abortion).

Would anyone believe that killing a newly born baby is murder without the influence of religion?
