Sorry, is crap.
Most churches do speak of the persecution of Christians around the world, they just do not do so in a way that would make them seem like a news hour on who is being persecuted every day.
They spend their time preaching the word and teaching about the precepts of God. If in the course of teaching they come to a message that touches upon one being persecuted for one’s belief, then they will mention it.
Some people are under the impression that a Pastor should spend the majority of their time speaking of the atrocities against Christians around the world, but they are wrong.
A sermon is about the Word, and bringing those listening into a better understanding of it, It is also about explaining why one must be saved.
Believe me, those in church know about Christians being persecuted around the world.
I am speaking inn general terms obviously, because there are those churches who are not following the gospel, but that is another topic all in it’s own.
