No, those who identify an act of witnessing, as an act of proselyting, do not understand Christianity.
No human being is able to ‘convert’ another human being into becoming a Christian. Conversion is the work of God.
Man can witness to one another, but we lack the power to convert. (When you find somebody with the ability to create human spirits, then they might be able to accuse them of converting somebody from being the old man to a new man.)
Sounds like you are doing a word dance just so you can feel right or just so you can argue with someone.
What do you think this apparently new Pentagon rule is talking about? It’s talking about witnessing or talking to others about Jesus. That’s what they or others mean by “proselytising”. Come on, man, talk about the real topic. Why do you feel the need to side track it with definition arguments?
