It is generally a bad idea to change your views based on a Wikipedia page. Particularly a Wikipedia page on a politically charged subject. What you see may only mean that nobody happened to stop by the page who was willing to add the negative examples.

Also, be careful that you don't read the article as saying more than it is actually saying. it says that "several people" on the right supported it. Great, at least two, and both of them from far enough in the past that "right wing" doesn't mean what it means today.
