:MastCell's actions are in support of Wikipedia's principles.  I'm glad that you found the edits I made constructive, but I'm frustrated by the disruptive nature of your comments.  The validity of a reference is not dependent on when it is published - more recent publications can provide greater insight as the science matures.  I added the references I did because I thought they were improvements, incremental though they were considering the wealth of information already contained in the rest of the article.  There is a FAQ at the top of this page that was established by consensus to address commonly-asked questions like the one you're asking (about the established links between HIV and AIDS).  I (and the many other WP editors) would be happy to work with you to improve WP further, but if you wish to continue this pattern of WP:Tendentious editing then I encourage you to take it elsewhere.
