I feel that it's something we all should do. I've been reading Primo Levi's book and I just can't imagine the level of suffering those people endured.
I mentioned it to an acquaintance and he said 'it's the sort of thing Jewish people do' and basically said I should not go, it would be depressing and there have been lots of other genocides. He has really annoyed me with these sentiments which come across as antisemitic imo.
