According to Danish newspaper "Kristeligt Dagblad" (Christian Daily Paper), the Dalai Lama thinks Christians and people in the West at large, should not convert to Buddhism:
"I hesitate a bit when I give lessons on Buddhism in Denmark and the West, because you have Christian traditions. It is better for you to keep your Christian traditions than change them and convert to Buddhism" -he allegedly said on a seminar about meditation.
This was in 2009, but I'm very surprised, actually. I'm not a follower of his tradition, but being such an important figurehead for Buddhism everywhere, I can't help but feel a little let down, and maybe even betrayed.
