Why are conservatives the only one who see that?
People don’t see on purpose. When you are so emotionally invested in an ideal, person, thought, or object, it is hard to look at that critically or rationally. They are completely missing the angle that these people (Cosby, Carter, Pelosi, etc) are also insulting Obama and every other African American by implying (or directly saying) they shouldn’t be treated as equals, instead they have some sort of deficiency and must be given previsions such as not having to deal with criticism or challenges.
