This meme assumes that Christians are obligated by their religion to do three things:
- Go to church
- Pray in public
- Talk about their lord and savior
And therefore, as long as those are permitted there can be no persecution.
However, this ignores the whole concept of negative commandments, things people are commanded by their religion not to do. For example, Quakers would consider themselves persecuted if conscripted into military service. Under Rome, Christians considered themselves persecuted when they were ordered to sacrifice to the Emperor and pagan deities.
