 | This is an essay. It contains the advice or opinions of one or more Wikipedia contributors. This page is not an encyclopedia article, nor is it one of Wikipedia's policies or guidelines, as it has not been thoroughly vetted by the community. Some essays represent widespread norms; others only represent minority viewpoints. |
 | This page in a nutshell: It's ok to express opinion on a userpage as long as it does not violate The wikipedia not policy. |
Some users have strong ideals that they may wish to post on their userpage; Sometimes these ideals are opinionated. Even if these ideas would be considered wrong for articles, they are perfectly fine for most user pages. Also some users may find it insulting for other users to constantly delete text on their user page and may cause a revert war. So just to keep civility on wikipedia try not to edit others userpages.
