Yes, actually, adding "references of his work" and then drawing conclusions from that is the very definition of OR. Regarding the material you added, I'm a little concerned about the quality. The first was fair, but the second was a blog, and the third didn't even refer to apartheid. Also, you can't generalize from one individual to a large group; if a Senator is objecting to something, then he is objecting to it, not some large unnamed group of people. (talk)
