I've seen more white people into Buddhism than Hinduism, but yes, Westerners are interested in Eastern religions. One reason is that they misunderstand the dharmic religions and feel they have "less rules" or be "more tolerant" than the Abrahamic religions. But this is not always the case, and I think many are sincerely seeking spirituality. They rightly see that Evangelical Christianity is the McDonald's of religion and because of its widespread influence, mistakenly believe all Christianity must be similarly bereft of wisdom so they go looking for it in the East.
