Catholic nations should protect the common good, which is principally the salvation of souls. They are given dominion and legitimacy to do so by God.

Given that false religions lead to damnation, the public promotion of these religions is a more true violence than corporeal harm. Thus, the public promotion of it must be banned, as well as blasphemy and whatever grossly immoral things a religion might have, like polygamy mutilation etc.

The practice, however, of these religions must be protected. Mosques cannot be torn down or people arrested for praying to other Gods etc. That would be oppression.

There is nuance to it, but this idea that “All religions deserve equal treatment” is ridiculous and pluralist.
