Evangelist, heal thyself

A conference on religious conversion organized by the Vatican and the World Council of Churches has issued a report (HT: Religion Clause) concluding that:

We affirm that while everyone has a right to invite others to an understanding of their faith, it should not be exercised by violating other’s rights and religious sensibilities. At the same time, all should heal themselves from the obsession of converting others.

I'm no fan of many tactics used for conversion.  That said, I'm not sure what "religious sensibilities" are, or what constitutes a violation of them.  I'm also a bit sketchy as to when a call to implement the Great Commission crosses the line into an "obsession" for which healing is appropriate.  Was St. Paul obsessed with converting others?
