Equality labs survey is anything but scientific. The participants were not carefully sampled. They say it was "community organized", which basically means it was a link that was propagated by activists to like-minded people to participate and pass the link on to.

> Muslims report the greatest degree of religious discrimination by far (39 percent), followed by Hindus (18 percent), Christians (15 percent), and believers of other faiths (9 percent). Sixteen percent of Indian Americans report being discriminated against by virtue of their Indian heritage. And, finally, 5 percent of all respondents report having encountered discrimination due to their caste identity.
