1) A meber of a language Google group I'm in suggested us Italki, I tried and so here I am...
2) I've never met racists here but it's mathematically probable there are some - really a few, I hope! I see racism every day even in my country (which pretends to be very civilized...!), just think our government is planning move against gipsy children! :(
So yes, discriminations (not only the racial one) are still a great serious problem!
