Ironically, a person like Ibrahim Ali provides a platform for Christians to become better Christians. Let me explain.
Have you ever wondered why when Jesus wanted to liberate Israel from tyrannical Rome (the government during his time)?
Instead of asking Rome to change, he sought to persuade Israel to change? Jesus felt that without the change of hearts in Israel itself, liberation in any form is impossible.
Jesus, at great length, explained that the resentment and bitterness that his fellow brethren carried in their hearts was nothing short of suicidal.
In fact he suggested that they be smart and read the signs of the times (e.g. in Luke 12:54-56) and not to follow the Zealots.
