I am surprised at how much Facebook has grown since I first joined back in 2004 when they only allowed college students (then quit a little bit later). Facebook has become the medium for people to connect, with other people, join groups related to their interest, and so... That is, as long as the Facebook administration doesn't feel they should censor and close down your group.
Chris Matyszczyk, writer for Technically Incorrect (CNet News), written an article based on the report that Facebook closed the group "I Hate Muslims in Oz" due to reasons labeled as "contained an explicit statement of hate." Facebook also plans to do the same with other groups, like Holocaust-denial groups, that have been reported.

I am completely against this action that Facebook is taking. If you read down the article it quotes.
He then went on to characterize the Facebook product as neutral: "Deciding what type of discussion should be allowed through a neutral tool for sharing, and what type of person would make an ideal employee at a company, are very different things, and we don't think our standards for the two should be the same."
How is censoring groups an act of being neutral? The best way to be neutral is to stay out of policing people on Facebook. I am a large advocate for free speech, especially when it comes to the internet. Ever since I first signed on some 14 years ago, I have dealt with internet companies who want to censor users to keep a damn 'nice' reputation (*cough* AOL) and all censoring does is start a trend of more and more censoring.
If you go on Facebook, you will see a lot of hate groups, and you will see a lot of groups telling Facebook to get the groups off Facebook. I say, let them both whine and don't get involved. Let freedom of speech truly prevail on the internet, and let anyone who wants to talk about whatever they want have the right to do so.
