I don't honestly know, but I hope so. Realistically, I think things are better now than they have been in the past, so hopefully things will continue to improve. On the other hand...I'd like to think that we could never have a country in which an extreme far right party was democratically elected to power, but the BNP continue to attract voters in the UK, and I'm sure there are other similar examples in other countries, so perhaps I'm being naive.
But I think that as new generations are born, they will hopefully be taught a set of values that don't make the assumption that if someone is different to you (whether that difference involves the colour of their skin, their gender, their sexual orientation, their political or religious beliefs), then that person is a fitting subject for hatred manifested at best as ridicule, and at worst as violence.
I think we're getting there. I hope we might get there in my lifetime.
