He's not asking that priests cease to be wounded, he's just stating that your suggestion would make it impossible for a hell of a lot of priests to maintain any kind of titles whatsoever.
What is wrong with that? I'd like to see examples where priests in the middle ages held a lot of high feudal titles. The ones that did certainly weren't spending their time preaching in some rural town where they could be attacked by 10 followers of a foreign religion.
Yeah, it is. Since I am still preaching to members of hostile religions that are in a region. When you're preaching, you're not preaching to your followers, you're preaching to pagans and other faiths. Pagans never attack. Hostile religions do, though there is a chance they can be stopped by followers.
If 90% of the religion follows you and 10% are evil heretics, you shouldn't be getting wounded. Your followers should protect you. Whether or not the game mechanics reflect this or not is for a different topic and proposal.
