^_^; the dwarf bit is.. well.. Tolkien wasn't anti-Semitic.. but he did kinda.. patronise Jews and put some of them into his take on Dwarfs... It's a bit like how I would very much say Lovecraft wasn't racist (I hate that word cause it directly refers to the old outdated view that things like skin colour denote 'sub-races' of humans.. Humans are ONE race. but that idea has been hard to fight and so they used stupid offensive terms like 'racist' but oh well) but he was very much fearful and afraid of many foreign things to a point where he had his huge break down when he was in New York for a while (which lead to 'The Horror out of Red Hook'). Even for his time, he was pretty sheltered which tainted his views, though he did write to a fair number of people.
I think alot of stuff shouldn't be 'edited' or just outright banned BUT warnings and given the correct context. Though the original creators CAN (if they want I have no real problem with it) edit stuff. Like how Hergé originally did little research when he did the newspaper strip 'Tintin', thus the.... bias view of the USSR and the Congo. later on, when he redid them for the Album versions, he did quite a few 'edits' to improve on the problem. Still in the current view, they are a bit iffy (Congo a while back was kinda 'banned' from the children's section in the UK and could only be sold as 'Adult graphic novel'. I think as with everything, as long as you have the context and stuff it's no a problem. Something which was meant as fun and no to offend, latter offends someone.. why take it out of context and say it was meant to be harmful? point out why some people are offended and let people know what's right or wrong. It's the same as when places like the USA tried to 'banned' cartoons like Tom and Jerry cause the parents couldn't be arsed to tell the kids 'you shouldn't hit someone on the head to make them lose there memory in real life' or 'squash them flat and expect them to be fine the next moment'. It is a cartoon. That is the context. It isn't real. Don't do this in real life..
sigh.. but the whole 'Lets just sit the kid infront of the TV and piss off to the party next door attuite remains as much today as in the 80s...
okay.. this is getting abit political.. but... I think Half Orcs are kinda.. ^_^ I'm sure you know how many cultures (like the USA, Vietiem, Japan, Korea) were HUGE against 'mixed race' children... like the poor half orcs
