Flawed Academic credentials

According to Wiki, Religious studies is an academic discipline, a field of multi-disciplinary, secular study of religious beliefs, behaviors, and institutions. It describes, compares, interprets, and explains religion, emphasizing systematic, historically-based, and cross-cultural perspectives. What religious studies does not do is educate or indoctrinate students to believe in a certain religion. Such studies are reserved for special religious schools, such as a yeshiva in Judaism, or a madrassa in Islam, or a seminary in Christianity. Religious Studies, in a university, does not teach dogma. It teaches a critique of any dogma in any religion.

This would seem like a foregone understanding of what Religious Studies does

Yet in Germany, a different precedent has been set:

After a revolt by German Muslims, a university is to appoint a new professor to oversee the training of schoolteachers in Islamic religious studies, officials said Tuesday.

Muslim organizations said last week they had lost confidence in Professor Muhammad Kalisch, the theologian who oversaw a teacher-training program at the University of Muenster in northern Germany.

Kalisch upset the Muslim community by writing that there was no historical evidence that the Prophet Mohammed existed.

Kalisch is doing what any academic in any field of studies has to do: he questions. Yet here he is, being bumped off a position at an academic institute because he does what an academic should be.

The term, Academia, connotes the cultural accumulation of knowledge, and its evolution across time and geography. Knowledge should be scientifically verifiable, well-argued, proved, based on facts and experimentation. Faith is not knowledge in the academic sense of the word. Believers may attest to feeling very strongly that their faith is knowledge, but since they cannot prove it by objective means, such knowledge is not academic: it may be religious, or intuitive, but academic, it is not.

So how come in Germany, they are going to pander to believers in choosing an overseer for a religious studies programme which is academic?

Why allow religious considerations dictate who is or is not competent to teach religious studies?
