But they didn’t care if you also worshiped the local gods. Not even an issue.

Therein lies the problem. Christians considered it apostasy if a so-called Christian offered a sacrifice to the pagan gods, even under threat of death. They called such individuals "traditores". There was an entire heresy devoted to not allowing traditores back into the Church after the persecutions ended called Donatism.
