White men dating indian women
I would imagine it'd be more likely with a Christian or irreligious Indian woman. There are quite a few Indians here anyway, but I notice they tend to stick with their own 'kind' moreso than other groups.
The more Westernised ones however do often date whites and others.
It does seem Indian parents are more conservative than even other Asians, and there seem to be few 3rd or 4th generation Indians living in Australia at least.
I think religion plays a large role in this as the number of Hindus, Sikhs, or Jains who aren't "Indian" are more or less negligible.
In my own extended family, the 1.5/2nd generation is all Americanized/Westernized but most of my "cousins" ended up choosing to marry other Indians.
Their culture is more closed off, they're more traditional, their families often disapprove.
Religion is a big part of their lives, whether Hindu, Muslim or Buddhist, so I don't know how they feel about inter-faith marriages.
