::@Figureofnine: Thank you. Your modifications appear to have resolved some legitimate issues regarding neutrality which had marred the article. @Nreganwiki: While you may have been well-intentoned in desiring to make the article more balanced, your changes  (a sampling: 
 ::, , , , ) were reverted because they were in direct violation of Wikipedia's policies, not to censor information (note, for instance that WP has an entire article on Walter Duranty). Per Wikipedia's stricture against original research - more specifically against original synthesis ("Do not combine material from multiple sources to reach or imply a conclusion not explicitly stated by any of the sources" - statements not explicitly made by reliable secondary sources cannot made in a WP article. (i.e. if no reliable sources can be located that clearly state there was a direct connection between Stalin's murderous exploits and the Hollywood blacklisting, then such cannot be stated in WP's mainspace ).  If you wish to edit this and/or other articles in the future, which you are most welcome to do, please also familarize yourself with policies on encyclopedic tone (keep it formal and non-conversational);  properly citing sources (i.e. directing readers, in the article's text, to "learn about" a particular subject crosses the line from citing to promoting - a practice prohibited on Wikipedia); assuming good faith on the part of editors who revert or alter your edits, as well the proper protocol for responding to such reverts/changes. Thanks.
