Come to US, especially the SF bay area and you will be proven outrightly wrong. I have seen in Santacruz a krishna temple run by white americans completely (including the archaks there). Hare Krishna has 2 lakh followers. More than 2 million in US practise Yoga and SriSri RaviShankar and AoL has a huge following including corporate. Baba Ramdev spoke in a UN Conf recently. Many churches are bought over and converted to temples in US/UK. Many muslims converting to Buddhism and Christianity in US. Growing presence of Vegetarianism and Yoga everywhere in US. In India, reconversion back to Hinduism going in full swing, lot of service activities by Sangh Parivar. It just requires confidence among hindus, after all Indians are hindus once.
