She got
fined $546 for holding two seminars in 2009 entitled "Basic Information on Islam," during which she likened Muhammad's marriage to a six-year-old girl, Aisha, to child enthusiasm.

The ECHR recognized that freedom of religion did not exempt people from expecting criticism or denial of their religion.
However, it found that the woman's comments were not objective, failed to provide historical background and had no intention of promoting public debate.
The applicant's comments "could only be understood as having been aimed at demonstrating that Muhammad was not worthy of worship," the court said, adding that the statements were not based on facts and were intended to denigrate Islam.
