An Offensive Invitation?

I am told on good authority that it is offensive to invite people of other religions to convert to Christianity. Thus it is offensive to say to a Jew, “Jesus is the Messiah and the Son of God and so you should be baptized and become a Christian”. It is similarly offensive to say to a Muslim, “Jesus is the divine Son of God and Muhammad was not a true prophet, nor is Qur’an His Word, and so you should be baptized and become a Christian”. It is also offensive to say to a Hindu, “Those whom you worship as Gods such as Vishnu, Shiva, and Krishna are not true Gods, but idols, and so you should be baptized and become a Christian”.
