It's also worth noting that these rituals included worship of the Caesars themselves. The rejection of an imposed faith then, necessarily, also included a rejection of empire.

The issue of being a good Roman citizen apart from worship of the Emperor was a key issue for early Christians. The answer was that they most certainly could do so, including serving in the army. It was obviously possible as after Rome became Christian it carried on for centuries.
I think that's a fair comment. Christianity being a matter of personal faith rather than government mandate was a core issue. Like many empires, Rome could not survive a world where the state itself was not the deity.
