Don't read too much into that, tons of places are quietly xenophobic while publicly they project a different image. There is huge difference big cities vs rural areas, don't expect simpler folks living few decades in the past to be very welcoming towards unknown.
Its slowly fading away from the face of the earth, but don't let some virtual bubbles like HN or physical ones like say SF or NY or western European big cities make the impression that this is how everybody there thinks.
People generally don't change their set-in-stone core opinions, critical thinking and self-reassessment is a privilege of relatively few, but they for sure learned to keep it to themselves these times.
