As stated before religious civics only affect cities with a religion. So, Theocracy absolutely DOES stop spreading of non-state religions to cities WITH state religion. If you have a city with no state religion then described occurance can very well happen.
Which is exactly the point I was making - did you even read what I wrote?
The person I was responding to said: "IT absolutely DOES stop spreading through trade networks, not just missionaries."
That statement is false. The only time religion spreads through trading networks is when a city has no religion. And if the city has no religion, then Theocracy won't stop it from gaining one.
