What Muslims say about Christian mission:
In the contemporary age, the Muslim community has been exposed to horrendous invasions and aggressive attacks, one of which is the missionary invasion that aims at uprooting the Muslim community altogether. This invasion began its missions with the Western colonialism (of the Muslim world), and it still exercises its activities in the Muslim world and among the Muslim communities and minorities (in non-Muslim countries). One of its goals is to entice Muslims to convert to Christianity. This goal was made clear in the North American Conference on Muslim Evangelization (that was held in Colorado in 1978). Forty studies about Islam and Muslims and how to spread Christianity among them were submitted to that conference, and US$1 billion was allocated for this purpose. In addition, the Zwemer Institute (in South Carolina) was established to train missionaries to preach Christianity to Muslims.
