People are scared of the unknown, that is natural. I’m going to a school with people from different countries. And to be honest, I was shocked at the beginning, but after 2 days it started to be ok. But when I look back, I can say I’ve learned from it (e.g. Don’t let the media fool you; people from other countries, races and so on are basically people, humans with hopes and dreams).
That’s why you have to give people time and of course a good place to be non-racist, non-homophobic, non-sexist.( you discovered yourself)
