I don't believe Christians are among the most persecuted in the world, no. Quite the opposite, they are the largest, most powerful and influential religious group on this planet today.
While there are without question countries where Christianity is disadvantaged, and Christians are subject to persecution, and while this is terrible and against religious freedom, which is a human right -
- all this being said, I also feel that a blanket statement like yours, implying that all Christians everywhere are being persecuted, severely diminishes the very real suffering of people who were and are being persecuted for their beliefs.
Your statement would benefit from a re-phrasing. As it stands, to me, it comes across as a rather crass reversal of the roles of victim and persecutor, given the historical and current demeanor of Christian majority countries.
