Speaking for Jehovah's Witnesses as Christians; we actually call it a 'com-mission'; or a 'mandate' from Christ Jesus. Our mission is found in Matthew 28:19:20, to witt: "All authority has been given Christ Jesus; THEREFORE - - GO - - Go make disciples of people of all nations; Baptize them; TEACH them all the commands of Jesus." Jesus and the early Christians actually did this, by their house-to-house ministry. There are other mandates also, but the above is Christians MAIN commission. This is the mission of Jehovah's Witnesses as Christians.
Either they do not trust your message or they do not trust Jesus'.
No, Buddhism did not teach baptism before Jesus. It is not part of that religion.
