My experience, it's Hindus and Muslims- predominantly from India. People from other parts of the state and country really don't understand how fast and comprehensive the changes have been. In this area, it's not a situation of women walking around in burkas and the evidence of Sharia law coming into play does not feel overt. So it seems less extreme than say the Muslims in Dearborn Michigan. But the gradual takeover of some cities over the last 5-10 years has been astounding.
On a personal level, my interactions with many different families have been fine. My daughter has gone to birthday parties and her school has maintained a high academic focus. But culturally, it's a dramatic shift. Foods, shopping centers, upkeep of homes/properties, celebration of holidays, personal hygiene differences, issues with more traffic accidents, differences in how they do business - everything is about haggling for a deal. Differences in the idea of personal space, difficulties in communicating due to English not being as dominant... it's very different to become a minority in America to a foreign culture.
