Might I also suggest that in certain cases, some people are hostile towards Jesus because of the hypocrisy, self-righteousness and abuses done by the church and self-proclaimed Christians?
Philip Yancey reported on this on his book, Vanishing Grace, where he discovered how many non-believers think of Christians (especially Evangelicals), not as bearers of good news, but as an elitist, esoteric group with a narrow and unrealistic view of the world and think themselves better than others for it. I actually remember hearing a Christian indie filmmaker at my training school testify about he found more support and encouragement from his atheist friends, while most of his were hostile and judgmental, and you might understand why many people don't view Christianity favourably.
Yancey (referrring to Lewis) describes such people as spiritual divorcees who been disillusioned by Jesus and Christianity thanks to those bad experiences, and unlike the "virgins" who never heard of the Gospel, they aren't going to be as easily won over by vague platitudes about Jesus's "love" and the typical and overused bumper-sticker quotes. They've heard it preached and not practiced, so to them the Gospel might sound more like a political propaganda than good news.
I don't think there's much we can say to convince them otherwise, but I suppose the best we can do is to continue to be gracious towards them, and pray that God will also send other Christ-like believers who can witness to them as well--since it's unlikely that they'd change their view on Christianity if you're the only one among hundreds of Christians who actually live out what they claim to believe.
