Some of nicest people I've met have been the east African Hindu and muslim community from Kenya and Uganda. One of the worst have been the Indian muslim Gujurati community. Faced racism and hostility from thier elders back in the early 90s. Even the Gujurati Hindus have been relatively peaceful towards me.
Bangladeshi, find them to be natural allies, not dealt with the ultra Bangla nationalits. Met some Bangladeshis and they have been neutral, they've also faced hostility from the racist indian Gujurati muslims.
Somalis, Afghans, Kurdish, Sudanese Syrian communities, elders are very cultured and respectful folks, youth are a major problem with emerging gang violence.
Only had limited interactions with Sikhs. Very positive with Afghan Sikhs.
White british, where I previously lived nice people, today things have dramatically changed.
Closest to me are my Pakistani brothers from Gujarat, Punjab. Love these guys. Mix feelings regarding mirpuries.
