Sadly it's true. But could you blame them? They have been forced for centruries to shut up, and renounce the faith of their fathers. And all this in the name of someone who (supposedly) does not exist.
You can bet however, that I would not be one of the vengeful. I would stick to the Christian principles, simply because I like them.
When Jesus said "blessed are the merciful for they shall obtain mercy". There are two option to keep in mind.
1. Either he is the Son Of God, and promises, that the merciful (no matter where they are coming from) will be shown mercy by him and his father. Or
2. In the worst case. He is just a man who suggested a better and more decent way of life, and taught the "Law of Attraction" (Like attracts Like). Eg. Mercy attracts mercy. Love attracts Love, Forgiveness attracts forgiveness. You get my point. Share your thoughts on that.
