Proselytising, in my opinion, is a person forcing their faith down the throats of others using threats if people don't convert. That brand of 'preaching' is highly unpleasant and abusive. I think it should be illegal if aimed at kids and the vulnerable!
Hi Floo, thanks for actually answering the question which so far everyone else has skirted around. However, I would disagree with your definition of the term. The Oxford dictionary defines it as the act of
Converting or attempting to convert (someone) from one religion, belief, or opinion to another
From a Christian perspective, no human can convert another human; all they can do is introduce them to God. It is the person, in conjunction with God, who chooses to convert.
What you describe is nothing more than abuse, and should have no place in a Christian's reportoire.
Interestingly, many developing nations use the term in the following way
encouraging a person to convert by offering inducements, such as food, a job or change in status
. This is how the Indian and Nepalese governments used to use the term, and the Christian missions in the countries were more than happy to accept such a ban.
