Using excessive force on a wife is wrong and that has always been the position of the Church. But that is a different issue from corporal punishment.
You appear to prefer going with your gut feeling to figuring out what the Church has taught. That is actually a characteristic of modernists.
The Church has not taught that wife-beating or excessive force is acceptable. Just because a theologian or two held the view does not mean that it has been an actual teaching of the Church.
This may be a good time to remind you that it hasn't been that long since you've given up some of your liberal views, especially regarding your support of ɧoɱosɛҳųαƖity and transgenderism.
It may be a case that you are going too far in the opposite direction, as a counter to your once liberal views. I was a liberal, too, at one time, but that was a long time ago.
