Some years back I reviewed some books on business in Asia on amazon.com.  One book I reviewed was completely awful, useless as advice and littered with racist BS.  It described the Japanese as ants and claimed (in effect) that one engine of of WW2 in Asia was Japanese hunger to eat Chinese flesh.  I wrote a review of the book, but a few days later discovered that it was censored by Amazon.  Amazon was fine selling the book, they just didn't want any "controversial" reviews.  Obviously I will never write another Amazon review again. 

Recently a post on my blogspot blog was also censored in the same way.  Obviously, I will not write another blogspot post again and will close all my gmail accounts.

There appears to be a problem with freedom of speech on American websites.  The land of the free, isn't so free after all and censorship is commercialized.
