Pfft, who could give a fuck. Most of white Buddhists and Hare Krishnas I've met are are weird Orientalist hippies more than racist, patronisers*.
This partly applies to all the stuff regarding white people wearing bindis. I've not met an Indian younger than my parent's generation who wears bindis ONLY because it is expected/traditional. Or was forced to wear one at all. Sure there might be functions/occasions where wearing a bindi might be expected, but no one is going to bust a nut because someone didn't.
The vast majority of Indian people (at least those living in western/Anglophile countries) wear them for the same reason white people wear them: because they look nice.
* Arguably being an orientalist does make a person racist and patronising, but I'm sure you get what the difference is in that example.
