There is no freedom of speech on the internet. What happens on a private or public message board, game site, what have you, depends what the owners deem acceptable or not.
Well of course they shouldn't be harrassed. This being an online thing, those people who harrassed gays at WoW, Guildwars or whatever should be banned from playing in those communities.
Sie sprechen Deutsches? German is a harsh sounding language but I like it. Gaelic and the romance langauges that came from Latin are other languages I like.
Arabic, (the language that Isrealis speak), and the South Eastern Asian languages are down right annoying.
