Belgium: racist (from immigration to hotel security) and somewhat hostile.

India: very racist -- in ways you would not imagine -- place historically although not hostile.

Sweden: racist although not hostile.

Brazil: racist although not hostile.

Russia: racist and hostile.

Kuwait: racist.

On the opposite end of the spectrum, I find Argentina to be amongst the least racist places around along with the UAE. In the US, racism is very much on the decline, although there are significant pockets of it here and there.
